Three-dimensional boundary element analysis of electromagnetic wave scattering by penetrable bodies

摘要: A frequency domain boundary element methodology of solving three dimensional electromagnetic wave scattering problems by dielectric particles is reported. The method utilizes a computationally attractive surface integral equation containing only weakly and strongly singular integrals in the contrast to most formulations involving not but hypersingular as well. main advantage this fact that its part similar one appearing corresponding dynamic elasticity. Thus, well known advanced integration techniques used successfully elastic can be directly applied present analysis. Both continuous discontinuous quadratic elements are employed order accurately treat scatterers with smooth piecewise boundaries. Numerical examples dealing demonstrate accuracy efficiency proposed formulation.
