Antenna radiation in stratified media
Abstract
A general wave field is treated as a superposition of the transverse electric and transverse magnetic fields, and general solutions are written inside a stratified medium, with the boundary conditions matched at the interfaces. The propagation matrices are defined to relate the wave amplitudes in different regions. The electromagnetic fields inside the region containing dipoles are determined by superimposing the primary excitations of the dipoles and the wave amplitudes due to the layered media above and below the dipoles. The fields in other regions are then readily calculated with the use of the propagation matrices. Numerical, analytical, and combined numerical and analytical methods useful for the evaluation of the field integrals are presented.
