Plane wave scattering from a large but finite strip array on dielectric substrate is analysed in the frequency domain via a decomposition into plane wave spectra by using the method of moments and a closed analytical form of the spectral Green's function for the structure under examination. Closed form asymptotic expressions are developed for mutual coupling terms which lead to a highly efficient and accurate procedure. New results for radar cross section in the ultra-wideband frequency range of the finite strip array are shown. Influence of the resistivity of the strips in the variation of the radar cross section is noted and discussed. Variations of the radar cross section with the scattering angle are presented as well.

Abstract
Plane wave scattering from a large but finite strip array on dielectric substrate is analysed in the frequency domain via a decomposition into plane wave spectra by using the method of moments and a closed analytical form of the spectral Green's function for the structure under examination. Closed form asymptotic expressions are developed for mutual coupling terms which lead to a highly efficient and accurate procedure. New results for radar cross section in the ultra-wideband frequency range of the finite strip array are shown. Influence of the resistivity of the strips in the variation of the radar cross section is noted and discussed. Variations of the radar cross section with the scattering angle are presented as well.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
