Abstract :
Iterative physical optics (IPO) is the iterative refinement of first-order PO surface currents to incorporate higher-order multi-bounce and multiple diffraction effects on electrically large geometries. The advantages of IPO are that it is a high-frequency asymptotic solution that does not require ray tracing, and can be applied to a general CAD surface mesh. This talk is an overview of the development of IPO and presents some new antenna and scattering applications.
