摘　　要：结合等离子体隐身技术在飞行器上的应用,讨论了电磁波斜入射到分层均匀的非磁化等离子体中的反射情况。根据波阻抗匹配原理,推导并得出了多层等离子体覆盖金属平板的反射系数。在不同等离子体电子密度分布下,当入射电磁波频率变换时,应用数值分析的方法得到了反射损耗随入射角变化和等离子体温度变化的规律,为等离子体隐身技术在飞行器和导弹上的应用提供了一定的依据。The reflection characteristic of electromagnetic wave incidence in non-magnetized plasmas with uniformed muliti-layer is discussed by combining with the application of plasma stealth technology in aircrafts.Based on wave impedance match principle,the reflection coefficient of muliti-layer plasma covering metal plate is deduced and completed.The reflection loss varying principle vs.incident angle and vs.plasma temperature is got by adopting numerical method in the case of different plasma electron density distribution as the incidence electromagnetic wave frequency changes,which provides a certain evidence to plasma stealth technology applied to aircrafts and missiles.
