The paper deals with a simple model of a dipole antenna radiating above a layered medium. The frequency domain formulation is based on the integro-differential equation of the Pocklington type. The influence of the earth-air interface is taken into account via the simplified reflection coefficient arising from the Modified Image Theory (MIT). The Pocklington equation is solved via the Galerkin-Bubnov variant of the Indirect Boundary Element Method (GB-IBEM). The related reflected field is determined by numerically evaluating field integrals. Some illustrative numerical results for the current along the dipole and radiated field above lower layered medium are presented.

Abstract
The paper deals with a simple model of a dipole antenna radiating above a layered medium. The frequency domain formulation is based on the integro-differential equation of the Pocklington type. The influence of the earth-air interface is taken into account via the simplified reflection coefficient arising from the Modified Image Theory (MIT). The Pocklington equation is solved via the Galerkin-Bubnov variant of the Indirect Boundary Element Method (GB-IBEM). The related reflected field is determined by numerically evaluating field integrals. Some illustrative numerical results for the current along the dipole and radiated field above lower layered medium are presented.| File | Dimensione | Formato | |
