High Frequency Scattering by a Second- Order Generalized Impedance Discontinuity on a Cylindrically Curved Surface
The aim of the present paper is to obtain explicit asymptotic expressions for the “transfer (diffraction) coefficients” related to the diffraction of high frequency cylindrical waves from the discontinuity occurred in the material properties as well as in the thicknesses of a coated cylindrically curved metallic sheet characterized by the second order GIBCs. Relying on the locality of the high ...
متن کاملHigh-Frequency Solution for Scattered Fields by Cylindrically Curved Conducting Surface
1. INTRODUCTION Recently, the studies on the scattering of electromagnetic waves by a cylindrically curved conducting open surface are becoming an important subject for a variety of applications [1]-[4]. When the geometrical ray or the creeping wave is incident on the edge of the cylindrically curved conducting open surface, the geometrical rays and the whispering gallery modes, which cling to ...
متن کاملHigh Order Generalized Impedance Boundary Conditions in Electromagnetic Scattering Problems
We briefly review the use and the derivation of Generalized Impedance Boundary Conditions (GIBC) in the case of thin dielectric coating and in the case of strongly absorbing medium, within the context of electromagnetic scattering problem at a fixed frequency. We then numerically test the validity and accuracy of these boundary conditions in the case of high absorption. A numerical treatment of...
متن کاملwater wave scattering by a surface discontinuity over a uniform porous bottom
scattering of an incoming wave train by a discontinuity at the upper surface of the ocean over a uniform porous bottom of finite depth is considered here in the framework of linearized water wave theory. by employing residue calculus method, the reflection and transmission coefficient are obtained. these coefficients are computed numerically for different values of the porosity parameter g and ...
متن کاملHigh-order high-frequency solutions of rough surface scattering problems
[1] A new method is introduced for the solution of problems of scattering by rough surfaces in the high-frequency regime. It is shown that high-order summations of expansions in inverse powers of the wave number can be used within an integral equation framework to produce highly accurate results for surfaces and wavelengths of interest in applications. Our algorithm is based on systematic use a...
