| 摘 要： | 利用搭建的实验测量系统,从放电单元数量、放电单元分布及放电电压三个方面进行实验,测量了柱状放电等离子体阵列对2~18GHz TM电磁波的透射衰减影响.结果表明,放电单元数量的减少可以改善等离子体对10~18GHz入射波的衰减效果;在整个2~18GHz范围内,等离子体放电单元之间取适当的间距可以提高等离子体对入射电磁波的衰减性能;放电电压的增大有利于增大衰减程度和扩大衰减频带范围.

| Abstract: | Influence of the cylindrical discharge plasma array on transmission attenuation of 2~18GHz TM electromagnetic wave was experimentally studied from the discharge unit numbers, the discharge unit distribution and the discharge voltage by the experimental measurement system. The results show that the transmission attenuation effect of the plasma on the incident electromagnetic wave in 10~18GHz can be improved by reducing the number of discharge units. In 2~18GHz, a proper distance between plasma discharge units can also do good for the attenuation performance. Increasing the discharge voltage is favorable for increasing the attenuation degree and expanding the range of the attenuation bandwidth. |
