Abstract
A method, based on the Full Wave Analysis (FWA) is presented to treat analytically and evaluate numerically the electromagnetic field sustained by an electric source inside an electrically biaxial grounded slab embedded in an isotropic homogeneous half-space in presence of a perfectly conducting finite patch located at the interface. As a prerequisite to this approach, the electric spectral (Fourier) dyadic Green's function of the structure is first developed and fully derived via the transmission-line analogy. Then the expression of the electric.field in each region of the space in terms of the spectral electric Green's dyad is given. The use of the boundary conditions allows us to determine a Spectral Electric Integral Equation (SEIE) for the electric current density induced on the scatterer's surface. The solution of the SEIE is carried out in the general case of location of the electric sources with the patch parallel to the interface. Numerical results for the radiated far-field, for the structure without the patch, with noteworthy information about the radiation on the horizontal plane and constraints on the electromagnetic parameters, thickness of the slab, working frequency and source position are presented and discussed. Finally, a numerical solution for SEIE, in order to evaluate the electric current densities induced on the patch, is shown.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
