Electromagnetic field computation in planar integrated structures with a biisotropic chiral grounded slab

A method, based on the Full Wave Analysis (FWA) is presented to treat analytically and evaluate numerically the electromagnetic field sustained by an electric point-source inside an electrically biisotropic chiral grounded slab embedded in an isotropic homogenous half-space in presence of a perfectly conducting finite patch located at the interface. 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 Integral Equation (SEIE) for the 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 input impedance of the structure and the radiated far-field with noteworthy information about the radiation on the horizon plane and constraints on the electromagnetic parameters, thickness of the slab, working frequency and source position are presented and discussed.
