THz Propagation Simulator

Abstract

Wireless communication with the carrier frequency at THz spectrum ranges brings many advantages such as higher volume of data traffics. The wave propagation at higher frequency ranges reveals, however, the unique characteristic, which is distinguished from the wave propagation at sub-6G frequency domains. As an example for that, wave propagation at higher frequency (e.g., sub-mm frequency) is susceptible to the atmospheric conditions such as humidity and rain. This implies to the importance of a new propagation simulator for THz frequency ranges, which covers the significant wave propagation behavior of THz frequency. This book chapter thus introduces a THz propagation simulator including both system level and link level simulator, with which the feasibility and the scalability of the wireless communication at sub-mm frequency domain can be identified. For that, this book chapter contains such topics across the board of THz simulator: the requirements of THz propagation for the simulator, the brief introduction of the software framework, the operation process of the THz propagation simulator with respect to system level simulation, as well as link level simulation and the corresponding simulation results. This chapter will give readers an overview of the THz simulator and its assessment possibility of the propagation channel with respect to the system level as well as the link level.
