Abstract

Closed form asymptotic representations are developed for the grounded planar single and double layer material slab Green’s functions. These asymptotic Green’s function are useful for the efficient determination of the currents on arbitrarily shaped microstrip configurations when employing a Moment Method (MM) solution of the integral equation for these currents. Previous work has in most cases employed either the Sommerfeld type integral, or the plane wave spectral (PWS) representation for these Green’s functions.
