Abstract

In this paper, according to Mie theory and the particle size distribution of fog droplets, the total absorption and scattering of group particle were analyzed, the extinction parameters and attenuation rate of the Terahertz wave were calculated in radiation fog and advection fog through Matlab programs, and the relationship between the visibility and coefficients of scattering, absorption and extinction were obtained. The extinction and attenuation of Terahertz waves with different wavelengths were compared and analyzed in two different fogs. The result shows that the extinction parameters will drop sharply when the visibility increases; the lower the frequency of Terahertz waves is, the smaller the extinction coefficients will be; and the extinction and attenuation of Terahertz waves in advection fog is stronger than that of Terahertz waves in radiation fog because of the larger fog droplet size.
