Closed-form Green's functions for stratified uniaxial anisotropic medium

Abstract

The spatial-domain Green's functions for electric and magnetic fields are cast into closed forms with two-level approximation of the spectral-domain Green's functions in the stratified uniaxial anisotropic medium. The spectral-domain Green's functions for general source and observation points are derived by the wave iterative algorithm. The explicit formulations reduced to the isotropic case agrees well with the existing results corresponding to the isotropic medium. By using the discrete complex image method, the closed-form Green's functions are obtained in the spatial domain. Numerical examples show that the closed-form Green's functions in the stratified uniaxial anisotropic medium have good accuracy and efficiency.
