Download High Frequency Electromagnetic Techniques books, Helps professionals find fast, accurate solutions to their design and analysis problems... The first and only single-source reference of its kind, this unique book offers a comprehensive, in-depth look at the state-of-the-art methods in high-frequency analysis. A superb working resource for researchers and designers in a wide range of industries, it includes detailed demonstrations of how these methods can be applied to design and analysis problems involving radiation, scattering, antennas on structures, mutual coupling, EMC and EMI studies, terrain propagation and modeling, and more. It is also designed to function equally well as a textbook for graduate-level courses in electromagnetics. Exhaustive coverage of the latest HF analysis techniques Practical solutions to a plethora of engineering problems Numerous case studies and illustrative examples Discussions of some of the computer codes currently used to perform high-frequency calculations and their relative merits and limitations. Electromagnetic engineers often deal with problems in which the surfaces of the geometrics being studied do not conform to the eleven coordinate systems in which wave equations are separable. In such cases, when exact solutions of wave equations don't apply, approximate methods must suffice. Among these is the class of high-frequency analytical techniques covered in this book—methods which lately have proven themselves to be indispensable to the design and analysis of radar systems, antennas, the interpretation of results in remote sensing, and the assessment of electromagnetic compatibility and electromagnetic interference in computer circuits. The most comprehensive guide to the subject currently available, High-Frequency Electromagnetic Techniques provides an in-depth look at the latest methods for high-frequency analysis. Designed to help professionals find fast, accurate solutions to their design and analysis problems, this valuable working resource features many case studies and realistic examples which vividly demonstrate exactly how high-frequency techniques can be applied to such areas as: Analysis of near and far field patterns of horns and corrugated conical horns and their design Analysis and design of various reflector systems Slot antennas and their high-frequency formulations and design Antennas on finite bodies and on aircraft The estimation of mutual coupling between antennas on structures EMC and EMI problems with aircraft antennas and antennas on structures Terrain propagation modeling and the prediction of the effects of terrain geometry and properties on EM wave propagation Ground, sea, and atmospheric clutter modeling and the choice of radar parameters to obtain clutter reduction in many situations Readers will also appreciate the fact that the author has devoted an entire chapter to detailed descriptions of all computer codes currently used to perform high-frequency calculations, including critical evaluations of their relative merits and limitations in a variety of applications, whenever possible. While it can serve as an excellent graduate-level text for courses in electromagnetics, High-Frequency Electromagnetic Techniques is, above all, an indispensable working resource for researchers and designers in the telecommunications, defense, and computer industries. It also has an extensive list of references and additional references which would be helpful to readers for further study.

Interaction Of High Frequency Electromagnetic Field With Biological Tissue Book Description

by Yinan Li, Interaction Of High Frequency Electromagnetic Field With Biological Tissue Books available in PDF, EPUB, Mobi Format. Download Interaction Of High Frequency Electromagnetic Field With Biological Tissue books, Understanding the interactions between high frequency electromagnetic waves with biological tissues, especially those in humans, are crucial in all aspects of today’s modern life where everyone is exposed to high frequency electromagnetic field, to some degree. More importantly, it can contribute to the design of electromagnetic medical imaging and therapeutic devices such as in the field of breast cancer detection and Transcranial Magnetic Stimulation (TMS). This dissertation is an attempt to provide a non-invasive and practical method for early detection of abnormalities occurred under human tissues particularly under breast tissue with the application to breast cancer detection and a novel coil design for Transcranial Magnetic Stimulation by exploring the relationship between high frequency electromagnetic field and the thermal reaction of biological tissue under the exposure of it. The presented work includes a detailed description of the relationship between the dielectric properties of biological tissue and the established electromagnetic (EM) field as well as the induced heat due to external EM field. Based on these relationships, a new design of coil has been proposed to solve one of the dilemmas encountered in TMS. Furthermore, a novel breast cancer detection technique was proposed based on traditional Thermal Imaging technique. Multi-physics simulations are used to demonstrate the validity of the operating characteristics of those techniques. A physical design of the coil and a prototype test bed for the detection technique was utilized to experimentally verify the feasibility of the method and the accuracy of the simulation results. The robustness of the detection technique was tested by using different simulation frequencies, different sizes of tumor tissue as well as different locations of the tumor. The results of this investigation indicates that the proposed methods and apparatus are feasible tools for use in the field.

Nonlinear Optics Book Description

by E. G. Sauter, Nonlinear Optics Books available in PDF, EPUB, Mobi Format. Download Nonlinear Optics books, The first complete guide to nonlinear theory and practice for engineers Nonlinear Optics is a highly accessible, applications-oriented introduction to a new and rapidly growing field. An indispensable resource for both electrical engineering students and professionals working in the telecommunications and optoelectronics industry, it: * Treats the subject of nonlinear optics in purely classical terms for electrical engineers * Offers numerous real-world examples clearly demonstrating the connection between theory and practical application * Features helpful chapter-end problems and numerous examples * Explores current and future applications of nonlinear optics in telecommunications, computers, and other fields Due to its many applications in fiber-optic communications and optoelectronics the propagation of light through nonlinear media is an increasingly important topic among electrical engineers. Unfortunately, books geared to the specific concerns of electrical engineering students and professionals in the telecommunications and optoelectronics industry continue to be in short supply. This book is designed to fill that gap. Nonlinear Optics is a complete, self-contained, applications-oriented introduction to the field. In an effort to make this book as accessible as possible to its intended audience, E. G. Sauter has foregone quantum mechanical descriptions, choosing instead to treat the subject of nonlinear optics in purely classical terms. He has also included numerous real-world examples that clearly demonstrate the connection between theory and practical application. The book begins with the theoretical foundations for the practical discussions that follow. Dr. Sauter treats the basic relations between polarization and electric field strength, the different nonlinear effects of polarizations of order two and three, wave propagation of complex phasors in nonlinear media and anisotropic media, and the conservation of energy and momentum in nonlinear processes. Over the six chapters that follow, these theories are applied to specific cases, including the linear electrooptic effects; second harmonic generation; parametric effects; four-wave mixing, including the Raman and Brillouin effects; and the optical Kerr effect. The remaining chapters present in-depth discussions of pulse propagation, solitons, and nonlinear effects in glass fibers. Helpful problems appear at the end of each chapter, and numerous worked and unworked examples are scattered throughout the text to elucidate principles and clarify complex material. A highly accessible, applications-oriented introduction to a new and rapidly growing field, Nonlinear Optics is an indispensable resource for both electrical engineering students and working professionals.
