Metamaterials are artificial materials with characteristics beyond those found in nature and that enable on-demand control of energy, waves and information to realise game-changing product performance, energy efficiency and functionality. Designed with structure and inclusions on the atom-to-wavelength scale, they underpin exciting emerging trends across a range of markets, e.g., telecommunications, aerospace, medical, sensors, automotive radar, imaging, anti-counterfeiting, camouflage, vibration suppression and more. Numerous market research studies predict significant growth, for example, by 2030 the metamaterial device market is expected to reach a value of over $10bn [e.g., Lux Research 2019].Conventional metamaterials have a response or functionality that is fixed at the time of manufacture. Furthermore, metamaterials often suffer from functionality only over a relatively narrow band of frequencies, whereas many of today's applications require multifunctionality and reconfigurability, while reducing size, weight power and cost. The topic of this proposal, tunable, reconfigurable and programmable metamaterials and active devices, offers the potential of dynamic functionality in order to respond to external stimuli, or change functionality in real-time to meet specific application requirements. In our "A-Meta" collaboration we exploit synergies between the expertise and facilities of the University of Exeter's Centre for Metamaterial Research and Innovation (CMRI) in the UK, and the National Science Foundation Industry-University Cooperative Research Center for Metamaterials (CfM) in the USA. Together, we focus on three novel methods for enabling metamaterial tunability: phase-change-metasurfaces in the optical regime; photoexcitation of semiconductors for the microwave and THz; and polymer-loaded locally resonant meta-atoms for phononics and elastic waves. Our long list of project partners (Airbus, BAE Systems, Ball Aerospace, Bodkin Design, British Telecommunications, Dstl, Metamaterial Technologies, M.Ventures (Merck), NASA, Oxford Instruments, Phoebus Optoelectronics, QinetiQ, Thales, Transense Technologies, and Wave Optics) demonstrates the timely and strategic importance of active metamaterials and associated devices. Their letters of support detail strong relevance to applications such as wireless communication, sensing, filtering, imaging, consumer electronics, autonomous vehicles, RF devices, efficient and fast computing, high performance mechanical structures, manufacturing processes, and underwater sound control.

超材料是一种人工材料，其特性超出了自然界中的特性，能够按需控制能量、波和信息，从而实现改变游戏规则的产品性能、能源效率和功能。它们采用原子到波长尺度的结构和内含物设计，支持了一系列市场中令人兴奋的新兴趋势，例如，电信、航空航天、医疗、传感器、汽车雷达、成像、防伪、伪装、振动抑制等。许多市场研究预测会有显著增长，例如，到2030年，超材料设备市场预计将达到超过100亿美元的价值[例如，传统的超材料在制造时具有固定的响应或功能。此外，超材料通常仅在相对窄的频带上具有功能性，而当今的许多应用需要多功能性和可重构性，同时减小尺寸、重量、功率和成本。该提案的主题，可调，可重新配置和可编程的超材料和有源器件，提供了动态功能的潜力，以响应外部刺激，或实时改变功能，以满足特定的应用要求。在我们的“A-Meta”合作中，我们利用了英国埃克塞特大学超材料研究与创新中心（CMRI）和美国国家科学基金会超材料产学研合作研究中心（CfM）的专业知识和设施之间的协同效应。一起，我们专注于三种新的方法，使超材料的可调谐性：在光学制度的相变-metasurfaces;微波和太赫兹的半导体的光激发;和聚合物负载的局部共振元原子的声子和弹性波。我们众多的项目合作伙伴（空中客车、BAE系统、Ball Aerospace、Bodkin Design、British Telecommunications、Dstl、Metamaterial Technologies、M.Ventures（Merck）、NASA、Oxford Instruments、Phoebus Optoelectronics、QinetiQ、Thales、Transense Technologies和Wave Optics）证明了有源超材料和相关设备的及时性和战略重要性。他们的支持信详细介绍了与无线通信、传感、滤波、成像、消费电子、自动驾驶汽车、RF设备、高效快速计算、高性能机械结构、制造工艺和水下声音控制等应用的密切相关性。
