A Closed-Form Expression of the Electromagnetic Tensor Green's Functions for a Homogeneous TI-Anisotropic Medium

摘要

In this letter, the electromagnetic fields from electric and magnetic current source distributions located in an unbounded homogeneous transverse isotropic (TI)-anisotropic medium are determined. The expressions provide the closed-form tensor Green's functions needed in any integral equation formulation of the forward as well as the inverse scattering problems associated with scatterers embedded in a homogeneous TI-anisotropic medium
