Dyadic Green's Function for Quasi-Isotropic Generalized Soft-and-Hard Planar Surface

摘要

By use of the spectral-domain approach, the Weyl's identity and the technique of exponential-integral function, a simple and accurate closed-form expression is derived for dyadic Green's function of planar artificially soft and hard surface. The Green's function is expressed as the stun of three parts: primary field, image field reflected by a perfect electric conductor boundary and field created by a transmission-line current source.
