Terahertz (THz) communication is one of the key technologies for the sixth generation (6G) of mobile communications

offering enormous bandwidth and supporting ultra-high transmission rates with broad application prospects. THz channel modeling is fundamental to the design

simulation

and optimization of THz communication systems. The research on THz channels mainly encompasses channel measurements

characteristic analysis

and channel modeling. In this paper

firstly

the time-domain and frequency-domain channel measurement methods are introduced. Some recent research activities are also summarized

including research institutions

measurement scenarios

methods

and measured channel characteristics. Next

the propagation characteristics of THz waves are summarized

including the propagation mechanisms of electromagnetic waves in the THz band

the large- and small-scale parameters of the channel. Finally

prospective directions and challenges are outlined for future research in the THz channel

aiming to enhance the understanding and exploitation of this promising electromagnetic spectrum for 6G and beyond.
