TE-SCATTERING AND RECEPTION BY A PARALLEL-PLATE WAVE-GUIDE ARRAY

Abstract

TE-wave scattering and reception by a parallel plate waveguide array is investigated. A Fourier-transform technique is used to express the scattered field in the spectral domain. The boundary conditions are enforced on the conducting surface and the array apertures to obtain simultaneous equations for the transmitted field inside the waveguide. The simultaneous equations are solved to obtain the transmitted field in a series representation whose first term is the Kirchoff solution. The behavior of the far-zone scattered field and the transmission coefficient are studied in terms of the scattering angle, array size, and frequency.
