Abstract

Electromagnetic wave diffraction on a cylindrical dielectric grating 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. Angular and spectral dependencies of E-polarized wave through the dielectric grating are analyzed for different kinds of polygonal cross-section.
