This paper presents a fast hybrid physical optics - time domain integral equation (TDIE) scheme for analyzing transient scattering from electrically large, perfect electrically conducting (PEC) objects. The scheme requires the user to delineate regions on the scatterer where currents are computed either using a TDIE scheme or by PO. In non-PO regions, currents are updated by solving a time domain combined field integral equation by marching on in time. Everywhere else, PO updates are effected by considering not only incident fields, but also fields radiated by all currents on the scatterer. The computation of the latter fields is accelerated by the plane wave time domain (PWTD) scheme. Multiple PO bounces are inherently captured by this formulation. Several examples that demonstrate the efficacy of this solver will be presented.","PeriodicalId":173343,"journal":{"name":"IEEE Antennas and Propagation Society International Symposium. Digest.

They are obtained by introducing a suitable new set of combined spectra that exhibit all the desired properties. As a consequence, the final expressions of the spectra satisfy all the Malyuzhinets method conditions, the edge conditions, explicitly satisfy reciprocity and nicely reduce to the original Malyuzhinets solution for normal incidence. The importance of the achieved symmetry with respect to incidence and observation aspects, is further emphasized in extending the solutions to dipole source illuminations.","PeriodicalId":173343,"journal":{"name":"IEEE Antennas and Propagation Society International Symposium.
