Abstract

We examined the forward reflection from a randomly rough lossy dielectric surface and the accuracy of the forward reflection model. The moment method could be used to compute the forward reflection coefficient. We also examined the effect of correlation length on various correlation length and RSM height. The forward reflection coefficient of a randomly rough surface is computed by the (1) or (2), but the exponential term in (1) goes to zero for a large value of kh_rms. On the other hand, (2) is stable for a large value of kh_rms. But (1) and (2) are function of only the RMS height. We will show the effect of correlation length from reflection coefficient. We will also show the modify reflection model with correlation factor for forward reflection from a rough lossy dielectric surface.
