摘要
For the sake of meeting the demand of data rates at terabit (Tbit) per second scale in future networks, the terahertz (THz) band is widely accepted as one of the potential key enabling technologies for next generation wireless communication systems. With the progressive development of THz devices, regrading THz communications at system level is increasing crucial and captured the interest of plenty of researchers. Within this scope, THz channel modeling serves as an indispensable and fundamental element. By surveying the latest literature findings, this paper reviews the problem of channel modeling in the THz band, with an emphasis on molecular absorption loss, misalignment fading and multipath fading, which are major influence factors in the THz channel modeling. Then, we focus on simulators and experiments in the THz band, after which we give a brief introduction on applications of THz channel models with respects to capacity, security, and sensing as examples. Finally, we discuss some key issues in the future THz channel modeling.
