This book was released on 1974 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diffraction of an electromagnetic wave by a perfectly-conducting right-angled wedge with one surface covered by a dielectric slab or absorber is considered. The effect of the coated surface is approximated by a uniform surface impedance. The solution of the normally incident electromagnetic problem is facilitated by introducing two scalar fields which satisfy a mixed boundary condition on one surface of the wedge and a Neumann of Dirichlet boundary condition on the other. A functional transformation is employed to simplify the boundary conditions so that eigenfunction expansions can be obtained for the resulting Green's functions. The eigenfunction expansions are transformed into the integral representations which then are evaluated asymptotically by the modified Pauli-Clemmow method of steepest descent. A far zone approximation is made to obtain the scattered field from which the diffraction coefficient is found for scalar plane, cylindrical or sperical wave incident on the edge. With the introduction of a ray-fixed coordinate system, the dyadic diffraction coefficient for plane or cylindrical EM waves normally indicent on the edge is reduced to the sum of two dyads which can be written alternatively as a 2 X 2 diagonal matrix.

Download or read book Scattering and Diffraction by Wedges 2 written by Vito G. Daniele and published by John Wiley & Sons. This book was released on 2020-10-29 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book has a dual purpose. The first is to expose a general methodology to solve problems of electromagnetism in geometries constituted of angular regions. The second is to bring the solutions of some canonical problems of fundamental importance in modern electromagnetic engineering with the use of the Wiener-Hopf technique. In particular, the general mathematical methodology is very ingenious and original. It is based on sophisticated and attractive procedures exploiting simple and advanced properties of analytical functions. Once the reader has acquired the methodology, she/he can easily obtain the solution of the canonical problems reported in the book. The book can be appealing also to readers who are not directly interested in the detailed mathematical methodology and/ or in electromagnetics. In fact the same methodology can be extended to acoustics and elasticity problems. Moreover, the proposed practical problems with their solutions constitute a list of reference solutions and can be of interests in engineering production in the field of radio propagations, electromagnetic compatibility and radar technologies.

This book was released on 2021-02-28 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This exciting new resource presents a comprehensive introduction to the fundamentals of diffraction of two-dimensional canonical structures, including wedge, strip, and triangular cylinder with different boundary conditions. Maxwell equations are discussed, along with wave equation and scattered, diffracted and fringe fields. Geometric optics, as well as the geometric theory of diffraction are explained. With MATLAB scripts included for several well-known electromagnetic diffraction problems, this book discusses diffraction fundamentals of two-dimensional structures with different boundary conditions and analytical numerical methods that are used to show diffraction. The book introduces fundamental concepts of electromagnetic problems, identities, and definitions for diffraction modeling. Basic coordinate systems, boundary conditions, wave equation, and Green’s function problem are given. The scattered fields, diffracted fields, and fringe fields, radar cross section for diffraction modeling are presented. Behaviors of electromagnetic waves around the two-dimensional canonical wedge and canonical strip are also explored. Diffraction of trilateral cylinders and wedges with rounded edges is investigated as well as double tip diffraction using Finite Difference Time Domain and Method of Moments. A MATLAB based virtual tool, developed with graphical user interface (GUI), for the visualization of both fringe currents and fringe waves is included, using numerical FDTD and MoM algorithm and High-Frequency Asymptotics approaches.

Download or read book Compatibility Studies Volume Vi Appendix 5 Multi diffraction of Electromagnetic Waves by Two Successive Impedance Wedges written by Kuo-Chun Lang and published by . This book was released on 1968 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This theoretical study provides a pictorial view of the multi-wedge diffraction phenomenon. Physical insight into the scattered field from the second wedge can be gained from these results. Furthermore, because the problem is considered with general boundary conditions, this analysis also provides qualitative information on the effects of physical parameters such as the angle of incidence of plane wave, the surface impedances on the facets of each wedge, etc. on the multi-diffracted field. By varying these parameters, the solution automatically reduces to that of a class of well-known problems; for example, the diffraction of plane wave by two conducting half-planes, etc. In addition to its theoretical significance, the analysis of this problem can also be of great practical value. In the problem of electromagnetic wave propagation over irregular terrains, one usually approximates such irregularities as hills and mountain ridges by knife-wedges. With the aid of the general representation of the scattered wave obtained herein, a comprehensive understanding of the effects of successive obstacles on electromagnetic wave propagation can be acquired.
