Electromagnetic scattering by a dielectric cylinder partially covered by conductors
Abstract
Twodimensional electromagnetic scattering by a dielectric cylinder partially covered by zerothickness perfect conductors is studied. The impressed field is either transverse magnetic (TM) or transverse electric (TE) to the cylinder axis. The problem is formulated in terms of two coupled boundary integral equations in each case. For the TM case the unknowns are equivalent electric currents, and for the TE case they are equivalent magnetic currents. These integral equations are solved by the method of moments with pulse functions for expansion and point matching for testing. Numerical solutions are obtained for a thin rectangular dielectric cylinder partially covered by perfectly conducting plates, where the impressed field is either a TM or a TE plane wave.
