摘要: 为了研究太赫兹波在沙尘大气中的衰减特性,根据Mie散射理论计算了单次散射情况下沙尘粒子不同尺寸参数下的散射效率因子和不同散射角下的散射相函数值。并得到了具有一定尺寸分布的沙尘粒子的单位距离衰减和能见度的关系曲线。还利用Monte Carlo方法对太赫兹波在沙尘中的多次散射特性进行了模拟计算,分析了不同能见度和不同沙尘类型对太赫兹波传输过程中能量损耗的影响。结果表明:单次散射条件下沙尘粒子的散射主要受尺寸参数影响;沙尘能见度较低时必须要考虑多次散射的影响。研究结果对太赫兹技术在大气环境监测和烟尘和风沙的探测等方面的应用具有参考价值。

Abstract: For the purpose of studying the attenuation characteristics of terahertz wave in dust atmosphere, using the Mie scattering theory, the influence of the dimension parameters of particles on the scattering efficiency factor was simulated, and the value of scattering phase function under different scattering angles, in the condition of single scattering were calcutated. Besides, the relationship between the attenuation of terahertz wave per unit distance in dust particles with certain size distribution and the visibility was simulated. In addition, the multiple scattering of terahertz wave in sand-dust condition was simulated, using Monte Carlo method. And the energy losses of terahertz wave in different visibilities and different dust types were discussed. The results show that the attenuation of terahertz wave is mainly determined by the dimension parameter, in the condition of single attenuation; and the multiple scattering must be taken into account when visibility is low. The results provide a reference point for the application of terahertz wave in those areas such as environmental monitoring, soot and wind-blown sand detection.
