N2 - A hybrid method combining Maehly approximation with phase extraction technique is proposed to solve the wideband electromagnetic scattering problem of a rough surface. Maehly approximation has shown the advantages of high computational efficiency, great precision and easy processing in solving wideband scattering of an object. In the simulation of scattering from a rough surface, in order to improve the efficiency of traditional Maehly approximation, we first apply the phase extraction technique to acquire normalized induced currents, which change slowly with frequencies. Afterwards the Maehly approximation is utilized to calculate wideband electromagnetic scattering from a rough surface. Since the induced currents on the rough surface are converted to normalized induced currents by the phase extraction technique, less frequency points are needed in the interpolation for wideband scattering. Therefore, our hybrid method can improve the computational efficiency of the traditional Maehly approximation greatly. The numerically simulated results of the proposed hybrid method are in good agreements with those of method of moment (MOM).
