Recent advances in the fields of materials science and electromagnetics indicate that materials can be synthesized with any desired electromagnetic properties. Electromagnetics of Complex Media provides the appropriate understanding of optimum properties for a given application, addressing the needs of researchers who study electromagnetics as a base for those disciplines using complex materials. Examples include electrooptics, plasma science and engineering, microwave engineering, and solid state devices.The book emphasizes these aspects: Dispersive medium Tunneling of power through a plasma slab by evanescent waves Characteristic waves in an anisotropic medium Transient medium and frequency shifting Green's function for unlike anisotropic media Perturbation technique for unlike anisotropic media Adiabatic analysis for modified source wave All of the above topics use one-dimensional models. Brief discussions also include chiral media, surface waves, and periodic media. The text focuses on bringing out the major effects due to each kind of complexity in the medium properties. A plasma column in the presence of a static magnetic field is at once dispersive, anisotropic, and inhomogeneous - thus the author uses plasma as the basic medium to illustrate some aspects of the transformation of an electromagnetic wave by a complex medium. Early chapters use a mathematical model that usually has one kind of complexity. The medium is often assumed to be unbounded in space or has a simple plane boundary. The field variables and the parameters are often assumed to vary in one spatial coordinate. This eliminates the use of heavy mathematics and permits the focus to be on the effect. Electromagnetics of Complex Media aims to stimulate experimental and additional theoretical and numerical work on the effects that can be obtained by the temporal and spatial modification of the magnetoplasma parameters. The book also provides the new researcher with a quick primer into the theory of using magnetoplasmas for the coherent generation of tunable radiation.

This book focuses primarily on senior undergraduates and graduates in Electromagnetics Waves and Materials courses. The book takes an integrative approach to the subject of electromagnetics by supplementing quintessential "old school" information and methods with instruction in the use of new commercial software such as MATLAB. Homework problems, PowerPoint slides, an instructor’s manual, a solutions manual, MATLAB downloads, quizzes, and suggested examination problems are included. Revised throughout, this new edition includes two key new chapters on artificial electromagnetic materials and electromagnetics of moving media.

Readily available commercial software enables engineers and students to perform routine calculations and design without necessarily having a sufficient conceptual understanding of the anticipated solution. The software is so user-friendly that it usually produces a beautiful colored visualization of that solution, often camouflaging the fact that the program is executing the wrong simulation of the physical problem. Electromagnetic Waves, Materials, and Computation with MATLAB® takes an integrative modern approach to the subject of electromagnetic analysis by supplementing quintessential "old school" information and methods with instruction in the use of newer commercial software such as MATLAB and methods including FDTD. Delving into the electromagnetics of bounded simple media, equations of complex media, and computation, this text includes: Appendices that cover a wide range of associated issues and techniques A concluding section containing an array of problems, quizzes, and examinations A downloadable component for instructors including PowerPointTM slides, solutions to problems, and more Striking a balance between theoretical and practical aspects, internationally recognized expert Dikshitulu Kalluri clearly illustrates how intuitive approximate solutions are derived. Providing case studies and practical examples throughout, he examines the role of commercial software in this process, also covering interpretation of findings. Kalluri’s extensive experience teaching this subject enables him to streamline and convey material in a way that helps readers master conceptual mathematical aspects. This gives them confidence in their ability to use high-level software to write code, but it also ensures that they will never be solely dependent on such programs.

A Thorough Update of the Industry Classic on Principles of Plasma Processing The first edition of Principles of Plasma Discharges and Materials Processing, published over a decade ago, was lauded for its complete treatment of both basic plasma physics and industrial plasma processing, quickly becoming the primary reference for students and professionals. The Second Edition has been carefully updated and revised to reflect recent developments in the field and to further clarify the presentation of basic principles. Along with in-depth coverage of the fundamentals of plasma physics and chemistry, the authors apply basic theory to plasma discharges, including calculations of plasma parameters and the scaling of plasma parameters with control parameters. New and expanded topics include: * Updated cross sections * Diffusion and diffusion solutions * Generalized Bohm criteria * Expanded treatment of dc sheaths * Langmuir probes in time-varying fields * Electronegative discharges * Pulsed power discharges * Dual frequency discharges * High-density rf sheaths and ion energy distributions * Hysteresis and instabilities * Helicon discharges * Hollow cathode discharges * Ionized physical vapor deposition * Differential substrate charging With new chapters on dusty plasmas and the kinetic theory of discharges, graduate students and researchers in the field of plasma processing should find this new edition more valuable than ever.
