A Study of Composite Electromagnetic Scattering From an Object Near a Rough Sea Surface Using an Efficient Numerical Algorithm

The composite electromagnetic scattering problem from the randomly rough sea surface and an object nearby is effectively analyzed by the Extended Propagation-Inside-Layer Expansion (EPILE) combined with the Forward-Backward method (FBM) scheme. The formulation of the composite scattering is given, the efficiency and accuracy of the adoptive algorithm are verified, and several scattering characteristics under various parameters are numerically analyzed.
