MDS in the analysis of pre-fractal printed strip gratings

Abstract

In this paper, we present new method for the modeling of printed strip gratings. Our general approach for finite perfectly electric conducting (PEC) strip gratings printed on a dielectric substrate with a PEC ground plane is based on the parametric representations of the integral and pseudo-differential operators and Method of Discrete Singularities (MDS). Diffraction problem is first reduced to hypersingular integral equation. Then this equation is solved using the MDS. Finite-order Cantorian set strip grating is investigated numerically. Some of obtained results are presented.
