摘要
对沙尘环境下太赫兹波衰减特性进行研究,在国际电信联盟(ITU)大气衰减模型的基础上,增加了不同类型沙尘的影响。基于大气毫米波传播模型(MPM)预测了1THz内大气衰减特性;根据Mie散射理论计算了太赫兹波在沙尘环境下因沙尘颗粒产生的衰减;结合以上两种因素得出沙尘环境下太赫兹的衰减特性。本文的研究结果对太赫兹在沙尘环境下传输应用具有重要的参考意义,也为其他颗粒环境太赫兹波传输特性的计算提供了参考。
Propagation of terahertz wave in sand and dust environment is investigated in this paper.The effects of sand and dust are included to the atmospherical attenuation based on the International Telecommunication Union(ITU)standard.The atmospherical attenuation is calculated by using the atmospheric Millimeter-wave Propagation Model(MPM).The attenuation due to sand and dust is calculated according to the Mie’s theory.The total attenuation is predicted by summing up the atmospherical attenuation and the particle attenuation.The calculation results can provide reference for terahertz applications in sand and dust environment,as well as other particulate environments for assessment of terahertz wave propagation.
