A simple and accurate complex image interpretation of vertical antennas present in contiguous dielectric half-spaces

An efficient technique is developed to solve the important problem of vertical antennas located above and penetrating the interface between contiguous dielectric half-spaces. It begins by deriving the spectral expressions of the vector and scalar potential Green functions in terms of the TM wave spectral transmission coefficient. The complex image technique is used to derive simple, accurate, and rapidly convergent expressions of the full-wave spatial Green functions. The spatial Green functions are used in the moment method to model vertical thin-wire antennas residing above the penetrating the interface separating the contiguous dielectric half-spaces with and without loss
