Abstract
In the paper the electromagnetic scattering from an airfoil object situated above rough surface is investigated by a hybrid method combining physical optics (PO) with physical optics (PO). Both the scatterings of an airfoil object and the underlying rough surface are calculated by the PO method. And the mutual couplings between them are solved by the equivalence principle and multi-path scattering strategy. In order to validate our method, the numerical results of composite model are compared with the conventional MOM method for both HH and VV polarizations.
