Science College, Air Force Engineering University, Xi'an 710051

摘要

摘要: 为解决临近空间通信黑障问题，研究了不同入射角对等离子体鞘套中C波段（4~8GHz）电磁波传输特性的影响，分别采用均匀等离子体模型与高斯分布非均匀等离子体模型，根据电磁波在分层介质面的反射和透射传播原理，对不同角度下C波段通信电磁波的传输性能进行计算和对比分析.结果表明，入射波频率的增加以及入射角的减小有利于降低C波段的衰减值，提高透射率，使通信电磁波更有效地穿透等离子体鞘套，为解决临近空间通信黑障问题提供了理论依据.

Abstract: In order to solve the problem of communication blackout in near space, the influence of different incident angles on the electromagnetic wave propagation characteristics of C-wave band (4~8GHz) in plasma sheath is studied. The transmission performance of C-band electromagnetic wave are calculated and compared by using the numerical method with a uniform plasma model and a Gaussian distributed plasma model, respectively. Analysis results show that the increase of the incident wave frequency and the decrease of incidence angle are beneficial to reduce the attenuation value of the C-band, and to increase the transmissivity, which makes the communication electromagnetic wave more effectively in penetrating the plasma sheath. The conclusion provides a theoretical basis for solving the problem of communication blackout in near space.
