Precious metals are an indispensable material for many production processes and products in today's world, from welding rings to dental implants. Global precious metals market size was expected to grow continuously, reaching nearly US $435.07 bn in 2027. Laser Powder Bed Fusion (LPBF), an additive manufacturing (3D printing) technique, uses a high-powered laser to melt and fuse metal powder layer-by-layer together creating a 3D object. It allows us to produce highly personalized and customized products. Although precious metal 3D printing promises robust growth, precious metal alloys which can be used for 3D printing are limited. The project aims to design, develop, fabricate, and test high performance precious metal alloys specifically customized for LPBF, targeting applications in space, healthcare, glass manufacturing and jewellery. To achieve this goal, the project will pioneer and employ state-of-the-art techniques to produce and functionalize precious metal powder for testing and prototyping. The project involves collaboration between researchers from academic and industry, and will establish a research team and innovation facilities to address shared research challenges facing the precious metal additive manufacturing industry, contributing to the regional and national economic prosperity.

From Marconi's first transatlantic wireless transmission through Sir Henry Tizard's radar to modern cellular communications, the rapid advance of applied electromagnetics during the 20th century has changed our world. Now, in the 21st century, a new revolution in exploiting electromagnetism (EM) is emerging; one that brings together two recent developments: spatial transformations and the design and fabrication of novel electromagnetic materials. The idea of spatial transformations (ST) is to provide entirely fresh solutions to the distribution of the spatial arrangement of materials so as to enable new ways to manipulate the emission, propagation and absorption of EM radiation. This goes far beyond what can be accomplished with traditional materials in the form of lenses and mirrors, requiring both conventional materials and also those with properties that do not exist in nature (i.e., metamaterials). ST are at the heart of exciting ideas such as invisibility cloaking and optical illusion. To make the required exotic materials in large quantities, modern fabrication techniques will be needed, including the use of nano-composites and graded-index coatings. The material palette can be further widened by the inclusion of active metamaterials and superconducting dielectric composites. As an example of the type of application one may envisage, there is an increasing demand for wireless communications anywhere and at any time. However, many environments such as offices and crowded shopping centres contain obstacles and scatterers that lead to signals being 'confused'. Signals either reach places they ideally should not, or worse, are not accessible where they are required. Current methods try to deal with these problems by additional signal processing of the received signals, but this can only be seen as an interim fix. A more resilient solution would be to modify the local EM environment so as to ensure quality reception at any given location by, for example, making certain obstacles or scatterers 'invisible'. Materials and devices based upon the concept of STs offer the exciting prospect of warping electromagnetic space so as to overcome problems due to obstacles and scatterers. Such applications are at the heart of the QUEST project. We will build and demonstrate several devices in collaboration with defence, aerospace and communication stakeholders in the areas of healthcare, security, energy and the digital economy. QUEST solutions will place the UK in a leading position in this exciting area, pushing the conceptual boundaries whilst at the same time exploring the practical problems of design and manufacturability.The Programme Grant will bring together a new grouping of leading UK experimentalists and theorists from physics, materials science and electronic engineering to work together on the exciting opportunities and challenges emerging in the area of spatial transformations (STs) and electromagnetism (EM). The potential of the underlying ST approaches however have much wider applicability than cloaking alone, in arguably more important applications that span communications, energy transfer, sensors and security. However, theory and concepts are outstripping practical demonstration and testing, leading to a mismatch in what may be theorised and computed and what can be realised for impact in society and commerce. We contend that the timing is now ideal for UK theorists, modellers, manufacturers and engineers to work together to maintain the UK strength in this field, with a clear focus on the reduction to practice and demonstration of potentially radical new concepts and devices.

Inspired by recent scientific breakthroughs in the area of transformation optics (TO) and metamaterials, QMUL in collaboration with its partners and UK industries have demonstrated several novel antenna solutions which potentially offer new composite flat lens antenna, surface wave and metasurface devices that could be embedded into the skin of vehicles without compromising aerodynamic performance, representing a major leap forward for future technologies related to the Internet of Things (IoT), CubeSat and Space Communications. The potential of the underlying design approaches have much wider applicability in arguably all technical challenges as addressed above. For example, we extended the TO technique to design novel beam steerable antennas . Instead of moving or tilting the feed/reflctor, we employ an alternative way to manipulate the reflected emission by varying the permittivity of dielectrics derived from TO. This method has the merits of maintaining a flat profile, being capable of beam-steering and frequeny agility. Combining with appropriate feed designs, the system can be effectively be used as either a single radiator or an array fulfilling massive MIMO functions. In a broad sense, dielectric substrates with spatially varying permittivity and/or permeability can be regarded as a "magic black box", whose properties are programmable according to required functional requirements. In the proposed ANIMATE project, we refer to this magic black box as "software defined materials", since they demonstrate far-reaching capabilities well beyond conventional antennas and arguably in all devices and systems that exploit electromagnetic spectra. To enable this step change, a suite of novel advanced materials must be studied and developed, especially, active materials and structures with low loss, high tunability but low DC power dissipation are desirable. In addition, a robust biasing network is needed so that material building blocks can be individually controlled. In spite of the longstanding quest and intensive research over the years, this subject area still remains insufficiently explored. With ongoing advances in modelling and manufacturing tools, it is now possible to revisit some fundamental limits imposed on conventional materials and antenna designs. The vision of ANIMATE is therefore to unlock contributions and expertise from multiple disciplines, to develop a core programme of research on software defined materials, which will enable dynamic control of electromagnetic waves for applications in sensing, communications and computation. The ultimate objective of ANIMATE is to remove the traditional boundary between the designs of antennas and RF/microwave electronics as well as materials and devices, so that a generic material platform can be developed that is programmable and flexible for multifunctional applications integrating communication, sensing and computation. Specifically, in this project, we will: 1. Establish a holistic approach of software-defined materials for communication, sensing and computation, by building novel integrated and adaptive antenna technologies. 2. Integrate wireless sensor networks into the design of computer interface and control units for tunable materials to demonstrate and validate the wholly new concept of "networked materials" at subwavelength scales. 3. Exploit challenging applications of proposed antenna and material technologies with our core industrial partners at all stages of development: prototyping, manufacturing, toolbox validation, platform integration and testing. 4. Research novel active and tunable materials and investigate fundamental limits of relevant materials to industrial challenges. 5. Develop simulation tools that span from materials, device and process modeling with intricate complexities that open up the design domain significantly and enable the production of optimal structures with improved performance.

The overall aim of this new CDT is to generate a body of highly-trained, doctoral scientists and engineers expert in the emerging and economically important area of metamaterials and possessing the skills, knowledge and professional attributes required to meet the challenges of employment in industry, academia and other commercial or governmental spheres. We will provide students with a detailed understanding of metamaterials from fundamental theory right through to prototype device design. At the same time they will be formally trained in the wider professional and personal skills such as innovation, engagement, commercial awareness and, importantly, leadership. Metamaterials are widely recognized as one of the most significant recent technical discoveries, highlighted as a top-ten insight of the last decade by Science Magazine. They are also set to become a major economic factor. In 2011 the global market for metamaterials was worth $256M, and is predicted by BCC Research to grow to $760M million by 2016, and to reach almost $2 billion by 2021. While products based on metamaterials are appearing (e.g. metamaterial antennas in mobile handsets and spacecraft; heat-assisted magnetic recording; transparent conductors for displays; surface bound data transfer and noise barriers etc.), the UK must ensure that future developments in these areas are strongly underpinned at the fundamental research level and also supported by highly skilled practitioners. The Government report on "Technology and Innovations Futures: UK Growth opportunities for the 2020s" (2010) lists 'metamaterials' and 'carbon nanotubes and graphene' as two key advanced materials areas. The UK's Ministry Of Defence (MOD) regards metamaterials as a key emerging technology, specifically listing advanced optical materials, advanced materials, bio-inspired technologies, and micro and nano technologies, as key areas, all topics that are of direct relevance to this CDT proposal. We note the comment from Professor Young's (Dstl) letter of support: "Dstl fully supports your proposal as a timely and unique vehicle for training future scientists, engineers and leaders for the benefit of the wider UK defence and security sector." Our cohort-based training will also help fulfil one of Minister David Willets' key aims "To create a more educated workforce that is the most flexible in Europe." To meet this last aim and to stimulate future UK work in this fast moving materials area we will establish a new CDT in a broad range of metamaterials research with PhD training that has an embedded engagement with industry. We will, together with our collaborators from industry, governmental laboratories and universities overseas, strengthen the synergy between physicists and material engineers, building on our pre-existing excellence in metamaterials and functional materials research. The research focus will be on EPSRC's Physical Sciences theme, specifically the sub topics "Photonic Materials, Metamaterials" (one of only three "Growth" research areas for this theme), and "Plasmonics" (a "Maintain" area). In addition, our CDT is relevant to the EPSRC's grand challenges of "Nanoscale Design of Functional Materials", and "Quantum Physics for New Quantum Technologies". There is also significant overlap with the EPSRC ICT "Growth" research areas of "RF and microwave communications" and "RF and microwave devices", which also encompass THz devices. Our team of 33 academics are addressing key and topical challenges across a range of internationally competitive metamaterials research: from microwave metasurfaces to carbon nanotubes, from graphene plasmonics to spintronics, magnonics and magnetic composites, from terahertz photonics to biomimetics. With the recent recruitment of two world leading theoreticians in transformation optics plus new work in acoustics, we shall combine depth and breadth of metamaterial research linked to industrial and Government laboratory researchers
