Summary :

This paper discusses an efficient numerical calculation technique for scattering from three dimensional bodies of perfect conductors and dielectric materials. The key of this method is to express the scattering fields by the field generated by the distributed hypothetical dipoles (or the equivalent sources). Since the scattered field should be analytic in each homogeneous sub-domain of general scattering bodies, the equivalent sources to be used for expressing the scattered field in one of those sub-domains should be distributed outside of this space domain. Unknown vector currents of equivalent dipoles are solved by the generalized mode-matching method. Example scatterers discussed here are finite conducting and dielectric cylinders with rotationary symmetry. The results are discussed with comparative data obtained by other numerical method and also with experiments that we took.
