This book was released on 2018-12-11 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis was based on the work of Hollis C. Chen who developed the 'coordinate-free analysis approach' to solve the equations for a propagating electromagnetic plane wave. In the first chapter, the basic properties of the monochromatic plane wave were presented alongside the laws of reflection and refraction which are (as known) derived from the boundary conditions. At the end of this chapter I presented Chen's analytical model and then used it in my own specific application (which is the main theme of this thesis) in the second and third chapters to further apply the same analysis on two different plates: isotropic and uniaxial, respectively. After I presented Chen's system of equations and before I introduced my own application at the end of these chapters, I have literally derived step by step all of Chen's equations to facilitate a much easier access into this material (and more specifically to rectify a major flaw in Chen's derivations) for both of the professionals and beginners of Science and Engineering alike. I have also computationally simulated the mathematically-dynamic model of my application. Furthermore, I have visualized Chen's own mathematically-static abstract equations and corrected his aforementioned mistake.

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).

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.

Available in PDF, EPUB and Kindle. Book excerpt: Wave Fields in Real Media examines the differences between an ideal and a real description of wave propagation, where ideal means an elastic (lossless), isotropic and single-phase medium, and real means an anelastic, anisotropic and multi-phase medium. The analysis starts by introducing the relevant stress-strain relation. This relation and the equations of momentum conservation are combined to give 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. The 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. Presents the fundamentals of wave propagation in anisotropic, anelastic and porus media Contains a new chapter on the analogy between acoustic and electromagnetic waves, incorporating the subject of electromagnetic waves Emphasizes geophysics, particularly, seismic exploration for hydrocarbon reservoirs, which is essential for exploration and production of oil

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.

This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We develop the analysis for the propagation of free waves in a general anisotropic plate. We begin with a formal analysis of waves in a plate belonging to the triclinic symmetry group. The calculation is then carried forward for the slightly more specialized case of a monoclinic plate. We derive the secular equation for this case in closed form and isolate the mathematical conditions for symmetric and antisymmetric wave mode propagation in completely separate terms. Material systems of higher symmetry, such as orthotropic, transversely isotropic, cubic, and isotropic are contained implicitly in our analysis. We also demonstrate that the particle motions for Lamb and SH modes uncouple if propagation occurs along an in-plane axis of symmetry. We present numerical free-wave dispersion results drawn from concrete examples of materials belonging to several of these symmetry groups.

Download or read book Plane Wave Propagation Problems in Electrically Anisotropic and Inhomogeneous Media with Geophysical Applications written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Boundary value problems required for modelling plane wave propagation in electrically anisotropic and inhomogeneous media relevant to the surface impedance methods in electromagnetic geophysics are formally posed and treated. For a homogeneous TM-type wave propagating in a half space with both vertical and horizontal inhomogeneities where the TM-type wave is aligned with one of the elements of the conductivity tensor, it is shown using exact solutions that the shearing term in the homogeneous Helmholtz equation for inclined anisotropic media: [Equation 1], unequivocally vanishes and solutions need only be sought to the homogeneous Helmholtz equation for biaxial media: [Equation 2]. -- This implies that those problems posed with an inclined uniaxial conductivity tensor can be identically stated with a fundamental biaxial conductivity tensor, provided that the conductivity values are the reciprocal of the diagonal terms from the Euler rotated resistivity tensor: [Equation 3], [Equation 4], [Equation 5]. -- The applications of this consequence for numerical methods of solving arbitrary two-dimensional problems for a homogeneous TM-type wave is that they need only to approximate the homogeneous Helmholtz equation and neglect the corresponding shearing term. The self-consistent impedance method, a two-dimensional finite-difference approximation based on a network analogy, is demonstrated to accurately solve for problems with inclined uniaxial anisotropy using the fundamental biaxial anisotropy equivalence. -- The problem of a homogeneous plane wave at skew incidence upon an inclined anisotropic half space is then formally treated. In the half space, both TM- and TE-type waves are coupled and the linearly polarised incident TM- and TE-type waves reflect TE- and TM-type components. Equations for all elements of the impedance tensor are derived for both TM- and TE-type incidence. This offers potential as a method of predicting the direction of anisotropic strike from tensor impedance measurements in sedimentary environments.
