Transient Close-Range Electromagnetic Field Coupling between Loop Antennas at the Interface of Dissipative Half-Spaces

The problem of electromagnetic (EM) field short-range coupling between coplanar loop antennas located at the interface of two half-spaces with dielectric and conductive properties is solved analytically in the time domain (TD) via the Cagniard-DeHoop (CdH) technique under the diffusive approximation. It is demonstrated that the thus obtained closed-form TD analytical expressions can be applied to evaluate the close-range EM-field signal transfer between two loops lying on the surface of a dissipative half-space.
