Simulation of Multiple Scattering of THz Wave Propagation in Sandstorm
View through CrossRef
Abstract
Terahertz wave has important application prospects in communication, but its transmission in the atmosphere will be affected by the atmospheric environment. Based on Mie scattering theory and Monte Carlo method, the attenuation characteristics of THz wave multiple scattering caused by dust storms in Tengger desert are studied in this paper. The relationship between the attenuation rate and visibility and frequency of THz wave are obtained by calculation. The results show that the multiple scattering of THz wave in sandstorm is very significant. There is a big error in the calculation of attenuation rate based on single scattering. The difference between the two methods decreases with the increase of visibility. The attenuation rate of THz wave varies with the frequency in the sandstorm. When the frequency of THz wave is less than 2.4 THz, its attenuation rate increases with the increase of frequency, and when the frequency is more than 2.8 THz, its attenuation rate decreases with the increase of frequency.
