Simulating of electromagneticscattering by two thin parallel dielectric cylinders

The problem of electromagnetic scattering by two thin parallel dielectric cylinders is solved inthe resonance frequency range by means of the auxiliary sources method. The gist of the usedmethod is the following. The unknown scattered field in the exterior medium is representedthrough the fields of electric- and magnetic- current filaments located on the axis of the cylindersand the fields in the interior of the cylinders are represented through the fields of auxiliary electricdipoles located on the auxiliary surfaces similar to the surfaces of the cylinders. To find the unknownelectric- and magnetic- current distributions along the axes and the unknown dipole momentsof auxiliary dipoles we use the boundary conditions on the surfaces of the dielectric cylinderswhich are satisfied according to the collocation method. Based on the method describedabove we developed a computer code for calculating the scattered - field components. We presentsome results of scattering cross-section calculations for cylinders of different length for differentangles of plane wave incidence.
