| 摘 要： | 应用高功率微波大气传输机理和等离子体物理理论，提出了一种新概念天线-等离子体有源透镜天线。简要概述了其实现方法，并对其反射、透射、吸收、工作带宽和最佳工作频率等特性参数进行了分析与计算。该天线根据需要可聚束ＨＰＭ工作波，也可将外来入侵的ＨＰＭ波聚束后发送回原处，可形成空间有源滤波等器件。

| Abstract: | Applying the mechanics of the propagation of high power microwave in atmosphere and the theory of plasma physics, a sort of new conception antenna-active lens antenna based on plasma is put forward.Its realization is summarized, characteristic parameters such as reflection, transmission, absorption, bandwidth and optimal frequency responding to different function are also analyzed and computed.As a result, this sort of antenna can be used to focus HPM operating waves or reflect transgressive HPM waves on the bass of forming passive filter device. |
