| 摘 要： | 利用荧光灯等离子体管覆盖金属腔体内壁，测量了筒状等离子体覆盖的金属腔体对电磁波的回波衰减。测试结果表明:金属圆筒内壁的等离子体能够有效吸收0.80~1.75 GHz波段的入射波，入射电磁波的回波衰减值为5~25 dB；当入射电磁波频率接近1.75 GHz时，回波衰减最为强烈,在入射角度为10°时，吸收峰值可达26.71 dB,因此选择合适的电磁波入射角度，能够使等离子体对微波的吸收达到峰值。理论分析了影响等离子体对电磁波衰减的主要因素。结果表明：等离子体可有效缩减腔体结构的雷达散射截面面积，因此在进气道等腔体结构的隐身方面具有一定的应用前景。

| Abstract: | A certain number of standard commercial fluorescent lamps were placed directly against one another around the inner surface of a metal cavity to produce a plasma layer there.The scattering of microwaves with a series of incident angles by the plasma covered metal cavity was studied experimentally.The strong loss of return microwave observed is as large as 5 to 25 dB in the frequency range from 0.80 to 1.75 GHz,and trends to a peak of 26.71 dB when the frequency of incident wave approaching to 1.75 GHz.The i... |
