This book presents a comprehensive exploration of electromagnetic wave propagation originating from a magnetic line dipole source placed at the vertex of a right-angled wedge. It delves into the fascinating realm of surface waves, which are generated when an impedance or mixed boundary condition is prescribed on one of the wedge's surfaces. The author skillfully employs an auxiliary function and partial differential equations to solve the complex wave equation and determine the amplitude of the surface wave propagated along the wedge's surface. The book also provides simplified expressions for the surface waves in both small and large l/k approximations. Through meticulous research, the author draws insightful comparisons between the surface waves produced by a line source at the tip of a right-angled wedge with impedance boundary conditions prescribed on both surfaces and the configuration presented in this book. The significance of this work lies in its contribution to the understanding of surface wave phenomena and its potential applications in various electromagnetic engineering domains.

Paperback. Condizione: New. Print on Demand. In this book, the author provides a detailed theoretical framework and practical solutions for understanding the behavior of surface waves in structures with multiple modes of propagation. Surface waves are a type of electromagnetic wave that travels along an interface between two different materials. The author presents a comprehensive analysis of surface wave excitation, propagation, and diffraction, providing valuable insights into the characteristics and applications of these waves. The book begins with an overview of the fundamental concepts of surface wave theory and presents a historical context for the development of the field. It then delves into the mathematical formulation of surface wave phenomena, including the derivation of boundary conditions and the use of integral equations to solve complex problems. The author also discusses the use of numerical methods, such as the finite element method, for modeling surface wave propagation in practical structures. One of the key contributions of this book is the development of a generalized impedance boundary condition that can be used to model a wide range of surface wave structures. This boundary condition provides a unified framework for analyzing the behavior of surface waves in structures with different material properties and geometries. The author also presents a detailed analysis of the far-field radiation patterns of surface waves, which is essential for understanding the performance of surface wave antennas and other devices. Overall, this book provides a comprehensive and in-depth treatment of the theory and applications of surface waves in multi-mode structures. It is a valuable resource for researchers, engineers, and students working in the fields of electromagnetics, antennas, and microwave engineering. The author's insights into the fundamental nature of surface waves offer a deeper understanding of their behavior and pave the way for further advancements in the field.

Paperback. Condizione: New. Print on Demand. This book presents a novel method for determining the diffracted far field caused by incident plane waves or line sources in the presence of an absorbing wedge. The author examines impedance boundary conditions valid for the case of an absorbing surface, while also considering surfaces that support surface waves. The book explores the relationships between these electromagnetic fields, explaining how one can be transformed into another. Complex mathematical derivations are used to provide solutions to these wave equations, resulting in precise formulas that define the far field radiation patterns. The author then applies these formulas to classical problems of diffraction by perfectly conducting wedges and half planes, providing both derivations and numerical examples. This book is an essential reference for researchers and students working in electromagnetics, antenna design, and related fields.

Paperback. Condizione: New. Print on Demand. This book presents a solution to a problem in the field of electromagnetism, that of determining the fields produced by a line source located at the corner of a right-angled wedge. The author uses an auxiliary function that satisfies the wave equation and simple homogeneous boundary conditions. The original field must then be determined by solving an auxiliary partial differential equation. The author explores the use of different mathematical techniques, such as the method of separation of variables, integration by parts, and the use of Green's functions. Along the way, the author derives several important double integrals and limiting expressions for certain important integrals that occur in the analysis. A comparison is made of the magnitude of the surface waves for a wedge and a plane in the limiting cases of l A) O and l -cc respectively, under the assumption that the source strengths in both cases are equal. Finally, the far fields for both configurations are determined. The book is a valuable resource for researchers and students in the field of electromagnetism.

Paperback. Condizione: New. Print on Demand. This book offers an exact solution to a wave diffraction problem for a three -dimensional right -angled wedge that partially absorbs radiation at certain angles of incidence. The author starts with a simplified boundary condition on one surface of the wedge and the usual boundary condition for perfect reflection on the other, which cannot be treated by the standard method of separation of variables. The solution is expressed as a well -defined boundary value problem that can be solved using quadratures. The method can also be applied to the problem of diffraction by an imperfectly conducting wedge and surface wave phenomena on wedges. Moreover, asymptotic solutions for the far field are also found. The book's insights provide a solid foundation for understanding wave diffraction problems involving partially absorbing or imperfectly conducting materials. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
