Abstract : The electromagnetic scattering from the sea surface at small grazing incidence is being examined numerically. Two numerical approaches, both extentions of the standard moment method (MM), are being used. The first is a hybrid approach that extends MM using the geometrical theory of diffraction. It has been used to examine the multipath scattering from a breaking ocean wave that may lead to sea-spike events and the effects of surface self-shadowing on distributed-surface scattering. The second approach is a periodic-surface implementation of the moment method. It has been used to examine the ability of the effects of finite surface conductivity on the scattering from wind roughened water surfaces.
