Investigation of Thickness Effects on the TM-Wave Radiation from a Thick Impedance-Loaded Parallel-Plate Radiator

Abstract

In this work, the influence of the plate thickness on the lowest order TM-wave radiation is investigated by using the mode-matching method in conjunction with the Fourier transform technique. While the classical formulation leads to an intractable matrix Wiener-Hopf factorization, the hybrid method adopted here reduces the related boundary value problem to a scalar modified Wiener-Hopf equation of the second kind. The solution involves infinitely many unknown constants satisfying an infinite system of linear algebraic equations susceptible to a numerical treatment. Some computational results illustrating the effect of the plate thickness and the plate impedances on the radiation phenomenon are revealed.
