Abstract

Recently an approach based on half‐space extraction technique was used to efficiently evaluate the electric field spatial Green's function on a surface. This Letter compares the results of this method with the mixed‐potential formulation in spatial domain. Both surface electric fields and impedance matrix elements for layered media are compared for source and observation‐point distances ranging from 0.1 free‐space wavelengths to 10 free‐space wavelengths. The results show two orders of magnitude improvement on the speed of convergence for Sommerfeld integration domain and better numerical stability. © 2002 Wiley Periodicals, Inc.

The electric fields of the spatial Green's functions of microstrip structures are calculated by numerically integrating the Sommerfeld integrals along the Sommerfeld integration paths. To facilitate and accelerate con¨ergence, a higher order asymptotic extraction is made in the integrand. The electr
