Scattering by a dielectric coated conducting elliptic cylinder

摘要

An exact treatment using the boundary value method for solving the problem of scattering of a line source field or a plane wave by a perfectly conducting elliptic cylinder coated by a confocal dielectric elliptical shell is presented. For the line source excitation the total field is calculated, while for the plane wave excitation the echo width is obtained. Sample and interesting results for the backscattering echo width versus different geometrical parameters are obtained and presented. A set of design type curves which are useful for locating the maximum or minimum backscattering echo width are also provided.
