Abstract

An integral equation approach based on domain decomposition method (DDM) is presented to solve antennas problems on electrically large platform. This proposed approach combines equivalence principle algorithm (EPA) and physical optics (PO). The number of unknowns decreases and computational efficiency increases. More importantly, EPA-PO avoids iterative Multi-Region procedure and obtains the final currents directly after considering interactions of different sub-domains. A numerical example will be shown to validate the approach.
