Considered is the scattering and absorption of an E-polarized two-dimensional (2D) beam generated by a complex-source-point (CSP) feed in the presence of a lossy grounded dielectric slab with a lossless superstrate. The solution is found analytically in the Fourier-transform domain. Numerical results demonstrate the ways of obtaining enhanced absorption in the slab by a proper selection of the slab electrical thickness and the parameters of the superstrate. The effects of internal resonances in the slab are analyzed and discussed.
