Paperback. Condition: New. Metamaterials, including their two-dimensional counterparts, are composed of subwavelength-scale artificial particles. These materials have novel electromagnetic properties, and can be artificially tailored for various applications. Based on metamaterials and metasurfaces, many abnormal physical phenomena have been realized, such as negative refraction, invisible cloaking, abnormal reflection and focusing, and many new functions and devices have been developed. The effective medium theory lays the foundation for design and application of metamaterials and metasurfaces, connecting metamaterials with real world applications. In this Element, the authors combine these essential ingredients, and aim to make this Element an access point to this field. To this end, they review classical theories for dielectric functions, effective medium theory, and effective parameter extraction of metamaterials, also introducing front edge technologies like metasurfaces with theories, methods, and potential applications. Energy densities are also included. …

Paperback. Condition: New. This Cambridge Element aims to advance theory by investigating the nature of participation in public service delivery. It situates itself under the theory of Public Service Logic to advocate for a strategic orientation to participation as an element of value creation in public services. It introduces the concept of participation and discusses the motives, incentives, and tools to engage citizens in public service delivery processes. Then, it frames citizens' participation under the approach public service ecosystem to capture the dynamic relationships among citizens, other actors, processes, and structures that may contribute to determining value in public service delivery. It presents the dynamics of value creation and destruction in public service. The Element concludes with implications for research and practice. This title is also available as Open Access on Cambridge Core.…

Paperback. Condition: New. Metamaterials have attracted enormous interests from both physics and engineering communities in the past 20 years, owing to their powerful ability in manipulating electromagnetic waves. However, the functionalities of traditional metamaterials are fixed at the time of fabrication. To control the EM waves dynamically, active components are introduced to the meta-atoms, yielding active metamaterials. Recently, a special kind of active metamaterials, digital coding and programmable metamaterials, are proposed, which can achieve dynamically controllable functionalities using field programmable gate array (FPGA). Most importantly, the digital coding representations of metamaterials set up a bridge between the digital world and physical world, and allow metamaterials to process digital information directly, leading to information metamaterials. In this Element, we review the evolution of information metamaterials, mainly focusing on their basic concepts, design principles, fabrication techniques, experimental measurement and potential applications. Future developments of information metamaterials are also envisioned.…
