Rough Surface and Delay Spread

抄録

This paper is concerned with the numerical analysis of electromagnetic wave scattering from a rough surface by using ray tracing method. The method is effective when the average height and correlation length of the rough surface are relatively large compared with the wavelength. First we check the accuracy of the present method in comparison with a rigorous solution to the strip diffraction problem. Second we show some examples of traced rays including reflected and diffracted ones. Finally we also show numerical examples for scattering and propagation characteristics peculiar to the rough surface problem.
