Abstract
ABSTRACT The study of the radiation from a vertical magnetic dipole in mi inhomogeneous half space and also in inhomogeneous stratified media above a horizontal conducting infinite plane is considered. The formal expression for the Hertz potential, from which all the field components can be derived. is presented in the form of a contour integral. These formal results are employed for special cases using suitable profiles for relative dielectric constants so that the electromagnetic fields can be expressed in terms of known functions. The contour integral is evaluated asymptotically by saddle point method of integration in each of the examples using special profiles for ε(z). Possibilities of the existence of surface waves in appropriate configurations are also discussed. The results for homogeneous media are also extracted from those of the corresponding inhomogeneous media by taking appropriate limits.
