Time-Domain Analysis of Horizontal Dipoles in Front of Planar Dielectric Interface

摘要

Time-domain solutions for fields due to an impulsive horizontal magnetic and electric dipole above a planar dielectric interface are studied analytically. General time-domain expressions for the Hertzian potentials corresponding to the electromagnetic fields in the upper medium are analyzed in a novel way by exploiting the Exact Image Theory. Additionally, the method has been used to derive analytic, closed-form solutions for certain special locations of the source and observation point. A part of the results is new and the rest coincide with the solutions in the literature.
