Abstract
Based on the reciprocity theorem, the far field formulation of an arbitrarily oriented electric dipole located at the interface of layered anisotropic half space is deduced. Then, considering the optical path difference of the direct wave and reflected wave, the formulation of the electric dipole located above the interface of layered anisotropic half space is discussed, and the transmission matrix method for computing the reflection coefficients of anisotropic layered half space is introduced in detail. Finally, numerical examples of the field produced by an electric dipole located above layered anisotropic half space are given. The numerical results show that this method can be used in the fast computation of far radiation field of an arbitrarily oriented dipole above layered anisotropic half space.
