Abstract
In this paper, we present an ultra-broadband terahertz (THz) channel model in typical office environment across a wide spectrum from 300 GHz (0.3 THz) to 310 GHz (0.31 THz). This ray-tracing model is used to study the indoor multipath propagation and its impact on terahertz channel by considering smooth and rough surfaces. These multipaths between Transmitter (TX) and Receiver (RX) are computed according to Kirchhoff Approximation, which accounts for specular losses by introducing Rayleigh roughness factor calculated from the surface height distribution. We employ the tangent plane approximation to scattering properties of common building materials in our propagation models which take Gaussian hypothesis on the height distributions into consideration.
