Effect of Surface Impedance on Radiation Fields of Spherical Antennas

Progress In Electromagnetics Research Letters, Vol. 71, 83-89, 2017
Abstract
Influence of surface impedance on radiation fields of spherical antennas excited by radially oriented electric dipole is investigated by using a Green's function for a space outside a spherical scatterer. This approach allows us to obtain analytical expressions for radiation fields of an impedance spherical antenna in the wave zone. The spherical antenna with the scatterer coated with a metamaterial layer is also considered. The surface impedance required for radiomasking of the spherical scatterer of resonant dimensions was estimated by mathematical modeling.
