Abstract

A domain decomposition scheme is presented to analyze broadband scattering by deep open cavities using the finite-element time-domain (FETD) and generalized scattering matrix (GSM) methods. The cavity is decomposed into less resonant subdomains, and each subdomain is characterized by a GSM which is obtained by the fast Fourier transform of the FETD solutions. The subdomain GSMs are then cascaded to form the broadband GSM of the cavity. After that, incident waves are expanded by the modes at the cavity aperture to calculate scattered waves using the global GSM and then the monostatic scattering cross-section. Numerical examples are presented to demonstrate the accuracy and efficiency of the proposed scheme.
