Abstract :
This paper deals with effects of sea surface roughness and wind direction on electromagnetic waves propagation in presence of evaporation duct. The Parabolic Equation method is used to solve the wave equation above a generated random sea surface which furthermore takes into account a roughness parameter. The wind direction influence on propagation is presented with numerical results of EM wave propagation.
