In this paper, the propagation properties of a terahertz (THz) wave in a collisional and inhomogeneous dusty plasma with a ceramic substrate and oblique angle of incidence are studied using the scattering matrix method. The influence of the various corresponding parameters, such as the frequency of the THz wave, angle of incidence, electron density, radius and density of the dust particles, and the collision frequency, on the absorbance and transmittance is calculated. The results of the simulation indicate that an increase in the wave frequency increases the transmittance and decreases the absorbance. Moreover, the absorbance of a THz wave in a dusty plasma with a ceramic substrate increases with an increase in the incident angle, maximum electron density, coefficient of steepness, density and radius of the dust particles, and collision frequency. These results provide an important theoretical basis for the problem of communication blackout between ground and spacecraft.

太赫兹波在陶瓷基底和倾斜入射角的碰撞和非均匀尘埃等离子体中的传播特性研究

本文利用散射矩阵法研究了太赫兹（THz）波在具有陶瓷基体的碰撞且非均匀尘埃等离子体中的传播特性和倾斜入射角。计算了各种相应参数的影响，例如太赫兹波的频率，入射角，电子密度，灰尘颗粒的半径和密度以及碰撞频率对吸收率和透射率的影响。仿真结果表明，波频率的增加会增加透射率，并降低吸收率。此外，随着入射角，最大电子密度，陡峭系数，尘埃颗粒的密度和半径以及碰撞频率的增加，在具有陶瓷基板的尘土等离子体中的THz波的吸收率增加。
