Dielectric Metamaterials
Dielectric Metamaterials: Fundamentals, Designs, and Applications links fundamental Mie scattering theory with the latest dielectric metamaterial research, providing a valuable reference for new and experienced researchers in the field. The book begins with a historical, evolving overview of Mie scattering theory. Next, the authors describe how to apply Mie theory to analytically solve the scattering of electromagnetic waves by subwavelength particles. Later chapters focus on Mie resonator-based metamaterials, starting with microwaves where particles are much smaller than the free space wavelengths. In addition, several chapters focus on wave-front engineering using dielectric metasurfaces and the nonlinear optical effects, spontaneous emission manipulation, active devices, and 3D effective media using dielectric metamaterials.
Metamaterial Electromagnetic Wave Absorbers
Electromagnetic metamaterials are a family of shaped periodic materials which achieve extraordinary scattering properties that are difficult or impossible to achieve with naturally occurring materials. This book focuses on one such feature of electromagnetic metamaterials—the theory, properties, and applications of the absorption of electromagnetic radiation. We have written this book for undergraduate and graduate students, researchers, and practitioners, covering the background and tools necessary to engage in the research and practice of metamaterial electromagnetic wave absorbers in various fundamental and applied settings. Given the growing impact of climate change, the call for innov...
Metamaterial
What Is Metamaterial A metamaterial is any material engineered to have a property that is not found in naturally occurring materials. They are made from assemblies of multiple elements fashioned from composite materials such as metals and plastics. The materials are usually arranged in repeating patterns, at scales that are smaller than the wavelengths of the phenomena they influence. Metamaterials derive their properties not from the properties of the base materials, but from their newly designed structures. Their precise shape, geometry, size, orientation and arrangement gives them their smart properties capable of manipulating electromagnetic waves: by blocking, absorbing, enhancing, or b...
All-Dielectric Nanophotonics
All-Dielectric Nanophotonics aims to review the underlying principles, advances and future directions of research in the field. The book reviews progress in all-dielectric metasurfaces and nanoantennas, new types of excitations, such as magnetic and toroidal modes and associated anapole states. Ultrahigh-Q resonant modes such as bound states in the continuum are covered and the promise of replacing conventional bulky optical elements with nanometer-scale structures with enhanced functionality is discussed. This book is suitable for new entrants to the field as an overview of this research area. Experienced researchers and professionals in the field may also find this book suitable as a reference. - Provides an overview of the fundamental principles, theories and calculation techniques underpinning all-dielectric nanophotonics research - Reviews current progress in the field, such as all-dielectric metasurfaces and nanoantennas, new types of excitations, associated anapole states, and more - Discusses emerging applications such as active nanophotonics with in-depth analysis
Metamateriale
Cos'è il metamateriale Un metamateriale è qualsiasi materiale progettato per avere una proprietà che non si trova nei materiali presenti in natura. Sono costituiti da assemblaggi di più elementi modellati da materiali compositi come metalli e plastica. I materiali sono solitamente disposti secondo schemi ripetitivi, a scale inferiori alle lunghezze d'onda dei fenomeni che influenzano. I metamateriali derivano le loro proprietà non dalle proprietà dei materiali di base, ma dalle loro strutture di nuova concezione. La loro forma, geometria, dimensione, orientamento e disposizione precisi conferiscono loro proprietà intelligenti in grado di manipolare le onde elettromagnetiche: bloccando...
超材料
什麼是超材料 超材料是任何經過工程設計的具有天然材料所不具備的特性的材料。它們由複合材料(如金屬和塑料)製成的多個元件組合而成。這些材料通常以小於它們影響的現象的波長的比例排列成重複的圖案。超材料的特性不是來自基礎材料的特性,而是來自它們新設計的結構。它們精確的形狀、幾何形狀、尺寸、方向和排列賦予它們操縱電磁波的智能特性:通過阻擋、吸收、增強或彎曲波,實現傳統材料無法實現的優勢。 您將如何受益 (I) 關於以下主題的見解和驗證: 第 1 章:超材料 第 2 章:超材料的歷史 第 3 章:負指數超材料 第 4 章:負折射 第五章:光子晶體 第 6 章:電子能帶結構 第 7 章:振盪 (二)回答公眾關於超材料的熱門問題。 (III) 超材料在多個領域的應用實例。 (IV) 17個附錄,簡述各行業266項新興技術,360度全方位了解超材料技術。 本書的讀者對象 專業人士、本科生和研究生、愛好者、業餘愛好者以及想要超越任何超材料的基本知識或信息的人。
メタマテリアル

Social Performance
Jeffrey C. Alexander brings together new and leading contributors to make a powerful and coherently argued case for a new direction in cultural sociology, one that focuses on the intersection between performance, ritual and social action. Performance has always been used by sociologists to understand the social world but this volume offers the first systematic analytical framework based on the performance metaphor to explain large-scale social and cultural processes. From September 11, to the Clinton/Lewinsky affair, to the role of the South African Truth and Reconciliation Commission, Social Performance draws on recent work in performative theory in the humanities and in cultural studies to offer a novel approach to the sociology of culture. Inspired by the theories of Austin, Derrida, Durkheim, Goffman, and Turner, this is a path-breaking volume that makes a major contribution to the field. It will appeal to scholars and students alike.
Meta Malzeme
Metamalzeme Nedir? Bir meta malzeme, doğal olarak oluşan malzemelerde bulunmayan bir özelliğe sahip olacak şekilde tasarlanmış herhangi bir malzemedir. Metaller ve plastikler gibi kompozit malzemelerden yapılmış çok sayıda elemanın birleşiminden yapılırlar. Materyaller genellikle, etkiledikleri fenomenin dalga boylarından daha küçük ölçeklerde tekrar eden modellerde düzenlenir. Metamalzemeler, özelliklerini temel malzemelerin özelliklerinden değil, yeni tasarlanan yapılarından alır. Kesin şekli, geometrisi, boyutu, yönü ve düzeni, onlara elektromanyetik dalgaları manipüle edebilen akıllı özelliklerini verir: geleneksel malzemelerle mümkün olanın ötes...
Fano Resonances in Optics and Microwaves
This book discusses the development of Fano-based techniques and reveals the characteristic properties of various wave processes by studying interference phenomena. It explains that the interaction of discrete (localized) states with a continuum of propagation modes leads to Fano interference effects in transmission, and explores novel coherent effects such as bound states in the continuum accompanied by collapse of Fano resonance. Originating in atomic physics, Fano resonances have become one of the most appealing phenomena of wave scattering in optics, microwaves, and terahertz techniques. The generation of extremely strong and confined fields at a deep subwavelength scale, far beyond the ...
