Technique of local secondary decomposition in solving two-dimensional electromagnetic problems by minimal autonomous blocks method

Abstract

A technique which makes it possible to use local secondary decomposition in two-dimensional version of minimal autonomous blocks (MAB) method is developed. The technique is validated for the problem of a plane electromagnetic wave diffraction on a periodic grating made from metal-dielectric strips. Developed technique can significantly decrease computational resources required for solving multiscale problems by the MAB method.
