In this paper, we analyzed the reflection and scattering characteristics based on the surface roughness of mediums at 60GHz, and studies a method for application to propagation prediction using a theoretical generalization of these characteristics. Due to short wavelength within a few millimeters of 60GHz band, the scattering characteristic is occurred by the small roughness of the surface of a wall on indoor environment. This means that the propagation prediction is impossible by analyzing the general reflection characteristic in order to analyze the propagation process of the radio wave by the surface roughness. Therefore, the reflection characteristic of the rough surface should be analyzed for a more accurate analysis. We proposed a propagation prediction method for indoor communication systems on the rough surface. These results can be enhanced the accuracy and reliability of ray tracing in the millimeter wave band.
