Haze can affect the optical properties of the atmosphere, so it is necessary to study the UV (ultraviolet) polarization characteristics of haze for atmospheric optical communication. The research focus of this paper is as follows: Based on the single-scattering polarization model of ultraviolet light, the Mie scattering theory and the T-matrix method are used for research. The polarization degree of ultraviolet scattering between spherical and ellipsoidal haze particles with different radii, different real and imaginary parts is simulated. The results show that the smaller the effective radius of the particle and the real part of the complex refractive index or the larger the imaginary part of the complex refractive index, the greater the maximum linear polarization degree. For ellipsoidal particles, the smaller the particle deformation, the greater the maximum linear polarization.
