Download or read book Anisotropic Propagation of Electromagnetic Waves written by Gregory Mitchell and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter will analyze the properties of electromagnetic wave propagation in anisotropic media. Of particular interest are positive index, anisotropic, and magneto-dielectric media. Engineered anisotropic media provide unique electromagnetic properties including a higher effective refractive index, high permeability with relatively low magnetic loss tangent at microwave frequencies, and lower density and weight than traditional media. This chapter presents research including plane wave solutions to propagation in anisotropic media, a mathematical derivation of birefringence in anisotropic media, modal decomposition of rectangular waveguides filled with anisotropic media, and the full derivation of anisotropic transverse resonance in a partially loaded waveguide. These are fundamental theories in the area of electromagnetic wave propagation that have been reformulated for fully anisotropic magneto-dielectric media. The ensuing results will aide interested parties in understanding wave behavior for anisotropic media to enhance designs for radio frequency devices based on anisotropic and magnetic media.

Available in PDF, EPUB and Kindle. Book excerpt: Authored by the internationally renowned José M. Carcione, Wave Fields in Real Media: Wave Propagation in Anisotropic, Anelastic, Porous and Electromagnetic Media examines the differences between an ideal and a real description of wave propagation, starting with the introduction of relevant stress-strain relations. The combination of this relation and the equations of momentum conservation lead to the equation of motion. The differential formulation is written in terms of memory variables, and Biot's theory is used to describe wave propagation in porous media. For each rheology, a plane-wave analysis is performed in order to understand the physics of wave propagation. This book contains a review of the main direct numerical methods for solving the equation of motion in the time and space domains. The emphasis is on geophysical applications for seismic exploration, but researchers in the fields of earthquake seismology, rock acoustics, and material science - including many branches of acoustics of fluids and solids - may also find this text useful.

Download or read book Radiation and Propagation of Electromagnetic Waves in an Anisotropic Medium written by Anatoliĭ Ivanovich Potekhin and published by . This book was released on 1973 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the work a systematic exposition is given of problems in the propagation of electromagnetic waves emitted by a sheet of current, an infinitely long filament, or an elementary dipole, in a uniaxial anisotropic medium. The field is calculated at an arbitrary distance from the source by rigorous methods. The orientation of the filament of current or the axis of the dipole is assumed to be parallel to or perpendicular to the axis of anisotropy. All problems are solved by a single method, in which the 'physical meaning' remains clear at every stage of the calculation. In all cases considered the solution is given in closed form (plane, cylindrical, conical, and quasi-spherical waves are considered).

Download or read book Terrestrial Propagation of Long Electromagnetic Waves written by Janis Galejs and published by Elsevier. This book was released on 2013-10-22 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terrestrial Propagation of Long Electromagnetic Waves deals with the propagation of long electromagnetic waves confined principally to the shell between the earth and the ionosphere, known as the terrestrial waveguide. The discussion is limited to steady-state solutions in a waveguide that is uniform in the direction of propagation. Wave propagation is characterized almost exclusively by mode theory. The mathematics are developed only for sources at the ground surface or within the waveguide, including artificial sources as well as lightning discharges. This volume is comprised of nine chapters and begins with an introduction to the fundamental concepts of wave propagation in a planar and curved isotropic waveguide. A number of examples are presented to illustrate the effects of an anisotropic ionosphere. The basic equations are summarized and plane-wave reflection from a dielectric interface is considered, along with the superposition of two obliquely incident plane waves. The properties of waveguide boundaries are implicitly represented by Fresnel reflection coefficients. Subsequent chapters focus on boundaries of the terrestrial guide; lightning discharges as a natural source of extremely-low-frequency and very-low-frequency radiation; and the mode theory for waves in an isotropic spherical shell. This book will be a useful resource for students and practitioners of physics.

Download or read book Electromagnetic Wave Propagation in Anisotropic Plasmas Along the Direction of a Static Magnetic Field written by M. P. BACHYNSKI and published by . This book was released on 1964 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental and theoretical investigation of the propagation of electromagnetic waves in an anisotropic plasma along the direction of the applied static magnetic field was conducted. Experimental measurements of electron density and attenuation using circularly polarized waves (left-hand or right-hand) show good agreement with theory and with each other over all ranges of parameters. For the right-hand mode at radio frequencies above the electron cyclotron frequency, 'cut-off' occurs at much lower electron densities than in the absence of a magnetic field. For the left-hand wave, both the phase change and attenuation decrease with magnetic field and the wave is affected much less by the plasma than the right-hand wave over the range of parameters encountered in the experiments. The theory of propagation of a linearly polarized wave in a lossy anisotropic plasma was derived. Investigations of the collisional effects on e-m wave propagation in the region of the electron cyclotron frequency show a reversal in phase of the wave passing through the plasma as the electron density is increased. This phenomenon occurs only for the right-hand circularly polarized wave at frequencies very near but just above the electron cyclotron frequency. Collisional effects based on cold plasma theory can account for this behavior.

This book was released on 2010-09-02 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: As technology matures, communication system operation regions shift from mic- wave and millimeter ranges to sub-millimeter ranges. However, device perf- mance at very high frequencies suffers drastically from the material de?ciencies. As a result, engineers and scientists are relentlessly in search for the new types of materials, and composites which will meet the device performance requirements and not present any de?ciencies due to material electrical and magnetic properties. Anisotropic and gyrotropic materials are the class of the materials which are very important in the development high performance microwave devices and new types composite layered structures. As a result, it is a need to understand the wave propagation and radiation characteristics of these materials to be able to realize them in practice. This book is intended to provide engineers and scientists the required skill set to design high frequency devices using anisotropic, and gyrotropic materials by providing them the theoretical background which is blended with the real world engineering application examples. It is the author’s hope that this book will help to ?ll the gap in the area of applied electromagnetics for the design of microwave and millimeter wave devices using new types of materials. Each chapter in the book is designed to give the theory ?rst on the subject and solidify it with application examples given in the last chapter. The application examples for the radiation problems are given at the end of Chap. 5 and Chap. 6 for anisotropic and gyrotropic materials, respectively, after the theory section.
Download or read book Theory of Magnetostatic Waves written by Daniel D Stancil and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic materials can support propagating waves of magnetization; since these are oscillations in the magnetostatic properties of the material, they are called magnetostatic waves (sometimes "magnons" or "magnetic polarons"). Under the proper circumstances these waves can exhibit, for example, either dispersive or nondispersive, isotropic or anisotropic propagation, nonreciprocity, frequency-selective nonlinearities, soliton propagation, and chaotic behavior. This rich variety of behavior has led to a number of proposed applications in microwave and optical signal processing. This textbook begins by discussing the basic physics of magnetism in magnetic insulators and the propagation of electromagnetic waves in anisotropic dispersive media. It then treats magnetostatic modes, describing how the modes are excited, how they propagate, and how they interact with light. There are problems at the end of each chapter; many of these serve to expand or explain the material in the text. To enhance the book's usefulness as a reference, the answers are given for many of the problems. The bibliographies for each chapter give an entry to the research literature. Magnetostatic Waves will thus serve not only as an introduction to an active area of research, but also as a handy reference for workers in the field.
