Abstract

This paper develops an efficient solution of vertical dipoles in contiguous dielectric half-spaces based on a mixed potential integral equation (MPIE) and moment method. Closed-form expressions for the spatial vector and scalar potential Green´s functions are obtained using the simulated image technique (Y.L. Chow et al, Proc. IEEE Int. Symp. Antennas and Propag., vol. 2, pp. 818-821, 1995). This technique has been used before for the computation of the periodic Green´s functions in multilayered media (R.M Shubair, Proc. IEEE Int. Symp. Antennas and Propag., vol. 3, pp. 1860-1863, 2001) as well as modeling of buried electrodes in multilayered media (R.M Shubair, ibid., vol. 4, pp. 838-841, 2001) and is extended here to model vertical antennas in contiguous dielectric half-spaces.
