Dyadic Green's Function for Electric Dipole Excitation of a Perfect Electromagnetic Conductor Sphere

In this article, we investigate the dyadic Green's function (DGF) of a perfect electromagnetic conductor sphere (PEMCS) due to electric dipoles, theoretically by employing the scattering superposition principle (SSP) and the Ohm-Rayleigh method. Then, the derived DGF is used to calculate the sc...

Description
Summary:In this article, we investigate the dyadic Green's function (DGF) of a perfect electromagnetic conductor sphere (PEMCS) due to electric dipoles, theoretically by employing the scattering superposition principle (SSP) and the Ohm-Rayleigh method. Then, the derived DGF is used to calculate the scattered field of a PEMCS due to an arbitrarily oriented infinitesimal electric dipole and also plane wave illumination. Numerical results are compared with those obtained by the FEKO commercial software to demonstrate the efficiency and accuracy of the proposed method. The results are in excellent agreement.
