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

TE-wave scattering and reception by a parallel plate waveguide array i s investigated. A Fourier-transform technique is used to express the s cattered field in the spectral domain. The boundary conditions are enf orced on the conducting surface and the array apertures to obtain simu ltaneous 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 coeffic ient are studied in terms of the scattering angle, array size, and fre quency.
