This book was released on 2013-08-13 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes a relatively new approach for the design of electromagnetic metamaterials. Numerical optimization routines are combined with electromagnetic simulations to tailor the broadband optical properties of a metamaterial to have predetermined responses at predetermined wavelengths. After a review of both the major efforts within the field of metamaterials and the field of mathematical optimization, chapters covering both gradient-based and derivative-free design methods are considered. Selected topics including surrogate-base optimization, adaptive mesh search, and genetic algorithms are shown to be effective, gradient-free optimization strategies. Additionally, new techniques for representing dielectric distributions in two dimensions, including level sets, are demonstrated as effective methods for gradient-based optimization. Each chapter begins with a rigorous review of the optimization strategy used, and is followed by numerous examples that combine the strategy with either electromagnetic simulations or analytical solutions of the scattering problem. Throughout the text, we address the strengths and limitations of each method, as well as which numerical methods are best suited for different types of metamaterial designs. This book is intended to provide a detailed enough treatment of the mathematical methods used, along with sufficient examples and additional references, that senior level undergraduates or graduate students who are new to the fields of plasmonics, metamaterials, or optimization methods; have an understanding of which approaches are best-suited for their work and how to implement the methods themselves.

Book excerpt: "The domain of metamaterials now covers many area of physics: electromagnetics, acoustics, mechanics, thermics, or even seismology. Huge literature is now available on the subject but the results are scattered. Although many ideas and possible applications have been proposed, which of these will emerge as a viable technology will only unfold with time. This book covers the fundamental science behind metamaterials, from the physical, mathematical, and numerical points of view, focusing mainly on methods. It concentrates on electromagnetic waves, but would also be useful in studying other types of metamaterials. It presents the structure of Maxwell equations, discusses the homogenization theory in detail, and includes important problems on resonance. It has an entire section devoted to numerical methods (finite elements, Fourier modal methods, scattering theory), which aims to motivate a reader to implement them. The book is not written as a collection of independent chapters but as a textbook with a strong pedagogical flavor."--Provided by publisher.

This book was released on 2012-12-15 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to provide an up-to-date introduction to the time-domain finite element methods for Maxwell’s equations involving metamaterials. Since the first successful construction of a metamaterial with both negative permittivity and permeability in 2000, the study of metamaterials has attracted significant attention from researchers across many disciplines. Thanks to enormous efforts on the part of engineers and physicists, metamaterials present great potential applications in antenna and radar design, sub-wavelength imaging, and invisibility cloak design. Hence the efficient simulation of electromagnetic phenomena in metamaterials has become a very important issue and is the subject of this book, in which various metamaterial modeling equations are introduced and justified mathematically. The development and practical implementation of edge finite element methods for metamaterial Maxwell’s equations are the main focus of the book. The book finishes with some interesting simulations such as backward wave propagation and time-domain cloaking with metamaterials.

Download or read book Mechanics of Metamaterials with Negative Parameters written by Teik-Cheng Lim and published by Springer Nature. This book was released on 2020-07-23 with total page 702 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses bulk solids that derive their mechanical properties not from those of their base materials, but from their designed microstructures. Focusing on the negative mechanical properties, it addresses topics that reveal the counter-intuitive nature of solids, specifically the negativity of properties that are commonly positive, such as negative bulk modulus, negative compressibility, negative hygroexpansion, negative thermal expansion, negative stiffness phase, and negative Poisson’s ratio. These topics are significant not only due to the curiosity they have sparked, but also because of the possibility of designing materials and structures that can behave in ways that are not normally expected in conventional solids, and as such, of materials that can outperform solids and structures made from conventional materials. The book includes illustrations to facilitate learning, and, where appropriate, reference tables. The presentation is didactic, starting with simple cases, followed by increasingly complex ones. It provides a solid foundation for graduate students, and a valuable resource for practicing materials engineers seeking to develop novel materials through the judicious design of microstructures and their corresponding mechanisms.

Available in PDF, EPUB and Kindle. Book excerpt: The rapid development of technology based on metamaterials coupled with the recent introduction of the transformation optics technique provides an unprecedented ability for device designers to manipulate and control the behavior of electromagnetic wave phenomena. Many of the early metamaterial designs, such as negative index materials and electromagnetic bandgap surfaces, were limited to operation only over a very narrow bandwidth. However, recent groundbreaking work reported by several international research groups on the development of broadband metamaterials has opened up the doors to an exciting frontier in the creation of new devices for applications ranging from radio frequencies to visible wavelengths. This book contains a collection of eight chapters that cover recent cutting-edge contributions to the theoretical, numerical, and experimental aspects of broadband metamaterials.

Download or read book Engineering Optics 2 0 written by Xiangang Luo and published by Springer. This book was released on 2019-02-28 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides comprehensive information on the history and status quo of a new research field, which we refer to as Engineering Optics 2.0. The content covers both the theoretical basis and the engineering aspects in connection with various applications. The field of Engineering Optics employs optical theories to practical applications in a broad range of areas. However, the foundation of traditional Engineering Optics was formed several hundred years ago, and the field has developed only very gradually. With technological innovations in both the fabrication and characterization of microstructures, the past few decades have witnessed many groundbreaking changes to the bases of optics, including the generalizing of refraction, reflection, diffraction, radiation and absorption theories. These new theories enable us to break through the barriers in traditional optical technologies, yielding revolutionary advances in traditional optical systems such as microscopes, telescopes and lithography systems.

This book was released on 2021-05-10 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium-Ionen-Batterien werden aufgrund ihrer hohen Energie- und Leistungsdichte häufig in Elektrofahrzeugen und stationären Speichersystemen eingesetzt. Allerdings müssen die Batteriezellen aufgrund der Kapazitätsstreuung ausgeglichen werden. Die Einzelzellschalter Topologie, die die Aktivierung und Deaktivierung jeder Batteriezelle basierend auf ihrem aktuellen Zustand ermöglicht, gilt als vielversprechende Lösung, um die Inhomogenität der Batteriezellen zu überwinden. Ziel dieser Arbeit ist die Entwicklung von optimalen Energiemanagement-Strategien für die Einzelzellschalter Batterie, um die Energieeffizienz des Systems zu maximieren. Für die Berechnung des globalen Optimums wird ein Optimierungsalgorithmus, basierend auf der dynamischen Programmierung Methode, entwickelt. Diese Strategie ist eine nicht-kausale Strategie, da die Batterieleistungsanforderungen über den Optimierungshorizont für die Strategie bekannt sein müssen. In einer Simulationsumgebung werden diese Informationen eines vorgegebenen Fahrprofils entnommen. Als nächster Schritt werden zwei statische Optimierungsprobleme von dem dynamischen Optimierungsproblem abgeleitet, damit die Entwicklung von kausalen Energiemanagement-Strategien ermöglicht werden kann. Diese Strategien berechnen ein lokales Optimum, da sie keine Informationen über den gesamten Fahrzyklus verwenden.
