Paperback. Condizione: New. Print on Demand. This book studies a vital function in the field of electromagnetic theory, known as the scattering amplitude. It is an integral part of understanding the intricacies of electromagnetism and acoustics. The author explores the properties of this function, leading to the development of new theorems and a significant conjecture. These findings provide fresh insights into the longstanding inverse scattering problem, which seeks to determine the shape of an object based on its scattering data. The interplay between the scattering amplitude, the shape of the scatterer, and the associated boundary conditions is meticulously examined. The book culminates in a fascinating result, known as the Circle Theorem, which provides a direct link between the scattering amplitude and the geometry of the scatterer. Through rigorous analysis and novel insights, this book deepens our understanding of electromagnetic and acoustic scattering phenomena, making it an invaluable resource for researchers and practitioners alike.

Paperback. Condizione: New. Print on Demand. This book establishes equivalence relations between different problems in diffraction theory, a branch of physics that studies how waves interact with obstacles. The author demonstrates that the solution to one problem can often be derived from the solution to a different one, using a technique called analytic continuation. This approach allows for the exploration of more complicated geometries and provides a deeper understanding of wave diffraction phenomena. The book is significant because it provides a new perspective on diffraction theory, opening up new avenues for research and practical applications in fields such as acoustics and electromagnetics.

Paperback. Condizione: New. Print on Demand. 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. This book explores the diffraction of a plane wave by a semi-infinite unidirectionally conducting screen. The author reduces the problem to the determination of a single scalar wave function. This wave function is then obtained explicitly in terms of functions associated with the diffraction by a perfectly conducting half plane. A simplified far field representation is found, and the solution is supported by an existence proof. The author shows that the idealization employed by Toraldo di Francia, whose work laid the groundwork for this study, is valid. The resulting solution is defined by a set of equations and asymptotic representations of the solution valid for large distances are indicated. The insights presented in this book on the diffraction of a plane wave by a unidirectionally conducting half-plane are significant for their contribution to the field of electromagnetics, as they provide a deeper understanding of the behavior of electromagnetic waves in the presence of such screens, enhancing our capability to design and optimize electromagnetic devices and systems.

Paperback. Condizione: New. Print on Demand. This book presents a complex mathematical formula to demonstrate a unique relationship between scalar and electromagnetic diffraction problems concerning a perfectly reflecting half plane with variable azimuthal angular orientations. The author begins with scalar wave propagation problems in which the half-plane's edge is excited by a ring source and extends to electromagnetic problems in which the propagation can be excited by sources with either longitudinal electric or magnetic current orientations. In addition, the author deep dives into the challenges in converting scalar solutions into vector solutions. The significance of this work is that it provides a comprehensive theoretical framework for understanding the diffraction of electromagnetic waves by perfectly conducting half-planes, which has important applications in antenna, radar, and microwave engineering.

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 is dedicated to understanding the electrical field behavior near the tip of a wedge-shaped conductor in the presence of a dielectric constant discontinuity. The author sets out to discover if the introduction of a discontinuity influences the singularity of the electrical field. The text presents a meticulous analysis of a specific conductor configuration and uses both electrostatic and electromagnetic principles to derive a Greenâs function for the system. The results are then generalized to arbitrary symmetric distributions of conducting material, providing a deeper insight into the behavior of electric fields near sharp edges and cusps in the presence of varying dielectric media. The book concludes by discussing the broader implications of these findings for understanding the behavior of electromagnetic fields in more complex systems, highlighting the significance of these insights for researchers and practitioners in the field of electromagnetism.

Paperback. Condizione: New. Print on Demand. This book offers an exact solution to the potential flow through a conical pipe, providing a solid foundation for further research in various disciplines. The solution has direct applications in diffraction theory, particularly in understanding the far field of sound waves arising from excitation within the conical pipe. The author's approach, while rooted in classical potential theory, is novel and characterized by the construction of integral representations of the solution using a variant of the Wiener-Hopf procedure. These representations are then used to obtain eigenfunction expansions of the potential, leading to explicit expressions for the conductivity of the conical pipe's opening. The behavior of the velocity of the fluid near the circular edge of the conical pipe is also determined, and the uniqueness of the solution is proven using the Rayleigh static method. The book's significance lies in its rigorous treatment of the problem, providing a framework for future investigations in fluid dynamics and acoustics.
