MPIE for conducting sheets penetrating a multilayer medium

A moment method procedure based on the mixed potential integral equation (MPIE) is presented to solve for the current distributions on the conducting sheets penetrating a multilayer medium illuminated by an incident plane wave. As usual, the vector potential is represented by a dot product of a dyadic kernel with the vector current density. Consequently, the scalar potential, which is related to the vector potential via the Lorentz gauge, cannot be described with a single scalar kernel. It is represented by a double dot product of a dyadic kernel with the dyadic charge distribution. We first present an MPIE with dyadic vector and scalar potential kernels. Then a moment method procedure is implemented to determine the current distributions induced on conducting sheets penetrating a multilayer medium. Finally, the numerical results are presented and discussed.<>
