Abstract :
In this paper, we present first results of ray-tracing simulations of a realistic office environment across a wide spectrum from 100 GHz (0.1 THz) to 1000 GHz (1.0 THz). This ray-tracing model is used to study the channel characteristics and analyze the variation in received power and the channel delay profile. Furthermore, the frequency dependent atmospheric attenuation has been considered in this contribution as an important parameter affecting each path in the ray-tracing model based on the ray-path length. We succeeded to incorporate the atmospheric attenuation models of International Telecommunication Union (ITU) with the ray-tracer results. A very detailed 3D model of the office environment has been drawn up while the parameters of the common building materials were taken from literature. Simulation results based on frequency sweeping will be presented. In the full version of this paper, time domain results would be illustrated with the corresponding channel parameters such as Delay Spread (DS) and Power Delay Profile (PDP).
