“…The numerical results accordance is noticeable in favor of EMAS. Figure 4 reveals the differential scattering cross-section k 0 σ d of dielectric circular cylinder with three inclusions of air holes as functions of observation angle Φ 0 , where parameters are identical with those in [4]. The number of auxiliary sources M = 100 and d aux is fluctuating around 0.07a 1 .…”

“…The EMAS results are compared with those given by the indirect matching method IMM, and the agreement between the results is obvious. Figures 8-10 show the backscattering cross-section of a dielectric circular cylinder with respectively one, two and three inclusions under TM plane wave incidence versus the eccentricity index step; all the parameters are identical with those in [4]. The incident wave frequency is set to 300 MHz.…”

Abstract-This paper establishes the extension of the method of auxiliary sources EMAS for the purpose of modeling the electromagnetic scattering response by jacket cylindrical structures constituted by a finite number of dielectric eccentric cylindrical inclusions embedded in a host dielectric one. Appropriate boundary conditions mixed with judicious decomposed domains leads to the prediction of the backscattering cross section. The algorithm also integrates the global electromagnetic coupling between the inclusions. The EMAS is validated by varying the inner cylinders repartitions and fine-tuning the electric permittivity according to different geometries. The EMAS level of accuracy compared with the indirect matching mode method IMM reveals a good agreement between the numerical computation results.

A plane electromagnetic wave scattered by two dielectric coated conducting strips is addressed here. Two methods of solutions are introduced. The first is based on solving the Helmholtez wave equation in terms of elliptical coordinates. As a result a Fourier series of radial and angular Mathieu functions of unknown coefficients in each region is obtained. The unknown coefficients can be obtained by enforcing the boundary conditions. The application of the boundary condition requires the use of the addition theorem of Mathieu function. The second method is based on an asymptotic approximate technique introduced by Karp and Russek for solving scattering by wide slit. Numerical examples are calculated using both methods and they are compared with each other. Excellent agreement between both cases is found.
