Waves in Metamaterials
Metamaterials is a subject born in the 21st century. It is concerned with artificial materials which can have electrical and magnetic properties difficult or impossible to find in nature. The mathematics of the book is within the power of final year undergraduates: the aim is to explain the physics in simple terms and enumerate the major advances.
Getting the Message
Getting the Message is a unique and engaging exploration of the fascinating history of communications, starting with ancient civilisations, the Greeks and Romans, then leading through the development of the electric telegraph, and up to the present day with email and smartphones. The technology is explained in a particularly simple and accessible way, and themes from politics, economics, and society weave in and out of the scientific ideas. The book concludes with a look at the possible future of communications, the new developments to come, and the implications these will have for our everyday lives. Lavishly illustrated, and including many original illustrations that show just how these new developments were received in their time, the book presents an informative and highly entertaining introduction to the field of communications. This revised second edition looks at the new developments in communications over the two decades since the first edition's release.
World Scientific Handbook Of Metamaterials And Plasmonics (In 4 Volumes)
Metamaterials represent a new emerging innovative field of research which has shown rapid acceleration over the last couple of years. In this handbook, we present the richness of the field of metamaterials in its widest sense, describing artificial media with sub-wavelength structure for control over wave propagation in four volumes.Volume 1 focuses on the fundamentals of electromagnetic metamaterials in all their richness, including metasurfaces and hyperbolic metamaterials. Volume 2 widens the picture to include elastic, acoustic, and seismic systems, whereas Volume 3 presents nonlinear and active photonic metamaterials. Finally, Volume 4 includes recent progress in the field of nanoplasmonics, used extensively for the tailoring of the unit cell response of photonic metamaterials.In its totality, we hope that this handbook will be useful for a wide spectrum of readers, from students to active researchers in industry, as well as teachers of advanced courses on wave propagation.
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...
Wave Optics
Wave Optics: Basic Concepts and Contemporary Trends combines classical optics with some of the latest developments in the field to provide readers with an appreciation and understanding of advanced research topics. Requiring only a basic knowledge of electromagnetic theory and mathematics, this book: Covers the fundamentals of wave optics, such as oscillations, scalar and vector waves, reflection and refraction, polarization, interference and diffraction, and rays and beams Focuses on concepts related to advances in negative materials and superresolution, reflectionless potentials, plasmonics, spin-orbit interaction, optical tweezers, Pendry lensing, and more Includes MATLAB® codes for specific research problems, offering readers a behind-the-scenes look at the computational practices as well as an opportunity to extend the research Drawing parallels with corresponding quantum problems whenever possible to broaden the horizon and outlook, Wave Optics: Basic Concepts and Contemporary Trends gives readers a taste of what is happening in modern optics today and shows why wave optics remains one of the most interesting and challenging areas of physics.
The Holodeck
This book is about a requirements specification for a Holodeck at a proof of concept level. In it I introduce optical functions for a optical processor and describe how they map to a subset of the Risc-V open instruction set. I describe how parallelism could be achieved. I then describe a possible layered approach to an optical processor motherboard for the datacenter and for a personal Holodeck. I describe Volumetrics in brief and show how its evolution to Holodeck volumetrics could be done with bend light technology and the possibility of solidness to touch. I describe in detail the architecture of a Holodeck covering several approaches to Holodecks from static scene to scrolling scene to multi-user same complex to networked multi-user Holodecks.
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...
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。
