Abstract

Electromagnetic wave diffraction on a cylindrical dielectric grating, inserted into a dielectric slab and placed on a dielectric substrate is considered. The problem is reduced to integral equation. Logarithm singularity of the integral equation kernel is extracted in explicit form that allows to solve integral equation changing integral by the high-precision quadrature formulae. Such analytical transformations result in high convergence of the algorithm.
