Analysis of antennas and scatteries of arbitrary shape in complex environments - the mixed potential integral equation approach

This work is concerned with the analysis of electromagnetic scattering and radiation by obstacles and antennas of arbitrary shape residing in complex environments. Our approach is to formulate an Electric Field Integral Equation (EFIE), which incorporates the effect of the environment by means of the appropriate Green's function, leaving the current distribution on the arbitrary surface as the only unknown. The Green's function is derived by the eigenfunction expansion technique, and the EFIE is solved numerically by the moment method (MM). We employ a particular form of the EFIE, known as the potential EFIE (MPIE, for short), which is amenable to isting, well-established MM procedures, developed for object free space. We discuss and compare two forms of the MPIE, one ba the Lorentz gauge, the other employing the less frequently Coulomb gauge.
