This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electromagnetic properties of a ferrite layer placed in front of a metal plate are investigated. For this purpose the reflection coefficient is measured as a function of the frequency with the thickness of the sample as parameter. The measurements are carrie out in a coaxial line with Ferramic E 1960 as test substance. In order to increase the bandwidth at larger t ickness of layer the ferrite is electrically shunted with a resistivity foil and the reflection coefficient of this combination is again measured as a function of the frequency. Parameters are the thickness of the ferrite layer and the surface resistivity of the foil. With this combination the operating frequency range is extended towards lower frequencies. Without resistivity foil the reflection coefficient remains about 10% in the entire range. (Author).

W. HELBERG and published by . This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two ferrite materals, Ferramic E and Ferramic E 1960, were used as magnetc layer absorbers. The measured reflection coefficients were below 10% in the frequency anges 4.2 x 10 to the 7th to 3.8 x 10 to the 8th and 2.4 x 10 to the 8th to 7.6 x 10 to the 8th, respectively. The thicknesses of layer were 0.88 cm and 0.5 cm respectively. These measurements confirmed the reflection coefficients calculated from the relaive dielectric constant and relative permeability. Various materials were tested with respect to their applicability as absorber material. (Author).

This book was released on 1966 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental method of realising an inhomogeneous transmission line for electromagnetic waves by sets of foils arranged one upon the other is described. There are two or three basic types of foils; one is lossless while the other contains lossy material. Inhomogeneous transmission line sections are obtained by constructing a set of foils of lossless and lossy foils alternately. The number of lossy foils can be varied from one set to the other in accordance with a given function. The measurements are made in a rectangular waveguide at some 4 GHz. (Author).
Download or read book Metamaterial Electromagnetic Wave Absorbers written by Willie J. Padilla and published by Morgan & Claypool Publishers. This book was released on 2022-01-24 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 innovations that can circumvent the use of conventional energy sources will be increasingly important. As we highlight in Chapter 6, the absorption of radiation with electromagnetic metamaterials has been used for energy harvesting and energy generation, and will help to reduce reliance on fossil fuels. Other applications ranging from biochemical sensing to imaging are also covered. We hope this book equips interested readers with the tools necessary to successfully engage in applied metamaterials research for clean, sustainable energy. This book consists of six chapters. Chapter 1 provides an introduction and a brief history of electromagnetic wave absorbers; Chapter 2 focuses on several theories of perfect absorbers; Chapter 3 discusses the scattering properties achievable with metamaterial absorbers; Chapter 4 provides significant detail on the fabricational processes; Chapter 5 discusses examples of dynamical absorbers; and Chapter 6 highlights applications of metamaterial absorbers.
