Abstract

Electromagnetic wave propagation over sea surface is affected by the surface roughness. In this paper, an improved impedance boundary method is presented and the initial field is calculated by Green function, which improves the stability and accurateness of the parabolic equation (PE). Eventually the forecast of propagation over rough sea surface has been presented with parabolic equation (PE). The results from PE are compared with Miller-Brown model, good agreement is shown.
