By applying scattering superposition principle and the Waterman's T-Matrix approach, a vector wave function expansion representation of dyadic Green's functions (DGF) is obtained for analyzing the radiation problem of a current source in proximity to a perfect conducting body of arbitrary shape. In the case of a conducting sphere, the general representation derived by using separation of variables method. Computations are implemented in Mathematica package for a dipole radiating in the presence of conducting spheroids and superspheroids.
