Modeling of plane electromagnetic wave scattering by dielectric cylinder

A numerical model was constructed based on the formal solution of plane wave diffraction by a dielectric cylinder that allows computing the scattered and complete field in the space around the cylinder for the cases of E- and H- polarizations. Spatial amplitude distributions are compared for dielectric and metallic obstacles at two frequencies (high and low) when incident plane wave has the E- and H- polarizations. Angular patterns are given for the complete and scattered electromagnetic field in case of the same frequencies and polarizations. The effect is analyzed similar to the Brewster phenomenon when a plane wave is incident of the flat dielectric interface. We demonstrate that the effect might be observed within some angular interval at a cylinder of large radius. © 2011 by Begell House, Inc.
