Mmds and 2d scattering problem by cylindrical structure with piece-wise smooth boundary

Abstract

An universal modification of the method of discrete sources (MMDS) was applied for solving 2D Dirichlet or Neumann boundary problem when the scatterer’s contour is a piece-wise smooth contour. The problems of accuracy, choosing auxiliary contours, stable results, location and type of contour’s break points are discussed. Keywords: Modification of the method of discrete sources, piece-wise smooth boundary, accuracy.
