| 摘 要： | 飞行器再入时会形成等离子鞘套,而等离子鞘套的形成会严重影响电波的传播,造成通信障碍。因此,需要研究电磁波在等离子鞘套中的传播特性,该文通过理论分析推导了电磁波在等离子体中传播的条件和沿不同方向传播时电磁波传播特性的计算方法。同时利用理论推导的结果来研究了电磁波在等离子体中的吸收特性和反射特性,其结果具有很高的准确性。

| Abstract: | The plasma sheath will be formed during aircrafts' reentry, and the formation of plasma sheath will seriously affect the spread of the waves, causing the communication barriers. In order to know the transmission characteristics of electromagnetic wave in plasma sheath, this paper deduces the precondition that electromagnetic wave can transmit and the computing method that electromagnetic waves transmit along different directions through theoretical analysis. At the same time, the characteristics of absorption of electromagnetic wave in plasma and reflection characteristics have been studied using the results derived from the theory, and the result has the very high accuracy. |
