300GHz terahertz wave scattering experiment and simulation from slightly rough surfaces on dielectrics

Millimeter and terahertz waves have been investigated to provide high-speed and large-capacity wireless communication. However, the short wavelength of such high-frequency bands would result in communication performance degradation due to wave blocking by obstacles and scattering by surrounding objects. In this paper, we focus on terahertz wave scattering from slightly rough surfaces. Scattering from dielectric surfaces was measured at 300GHz by using a simple experimental setup for stable and precise measurement. The measured results are compared with a numerical simulation based on our theory of stochastic functional approach.
