针对电磁波在蒸发波导中的异常传播现象,研究了电磁波在蒸发波导中的传播损耗,其传播损耗是电波传播的一个重要概念,并受到广泛关注。抛物模型(PE,Parabolic Equation Model)作为目前研究电波传播的主要模型,通过与Two-ray模型的对比分析验证了PE模型的可行性,且PE模型计算电磁波的传播损耗时可以克服其他模型预测粗糙海面时的不足。仿真分析表明,电波在蒸发波导中传播时的损耗值比在标准大气中的损耗值要小。
Aiming at the abnormal propagation of electromagnetic wave in evanescent waveguide, the propagation loss of electromagnetic wave in evanescent waveguide is studied. Its propagation loss is an important concept of electric wave propagation and has been widely concerned. Parabolic Equation Model (PE) is the main model for the study of radio wave propagation. The feasibility of the PE model is verified by comparison with the Two-ray model. The PE model can overcome the prediction of the roughness of other models when calculating the propagation loss of the electromagnetic wave. Insufficient sea time. Simulation analysis shows that the loss of electric wave propagating in the evanescent waveguide is smaller than the loss in the standard atmosphere.
