Plane Wave Scattering

This paper treats the low-frequency TM plane-wave scattering from a two layer double-strip grating with equal gaps. The problems solved by using a simplified network model which takes into account only the basic (n=0) mode. Numerical results are given for the magnitude of the basic mode reflection coefficient versus the relative grating period.

In this paper the problem of TE and TM plane wave diffraction from a two-layer grating in low-frequency case is presented. The problem is solved using the network model. Numerical results for the reflection coefficient of the lowest (n=0) mode versus frequency are given and compared to available results from literature.

Auxiliary Source

The method of auxiliary sources (MAS) is utilized in the analysis of Transverse Magnetic (TM) plane wave scattering from infinite, conducting, or dielectric cylinders, including curved wedges. The latter are defined as intersections of circular arcs. The artificial surface, including the auxiliary sources, is shaped in various patterns to study the effect of its form on the MAS accuracy. In juxtaposition with the standard, conformal shape, several deformations are tested, where the auxiliary sources are forced to approach the tip of the wedge. It is shown that such a procedure significantly improves the accuracy of the numerical results. Comparisons of schemes are presented, and the optimal auxiliary source location is proposed.
