摘要: 利用等离子体平面阵,依此研究50 MHz~3 GHz电磁波入射等离子体阵面所造成的衰减和反射.研究发现辉光等离子体阵面对入射电磁波具有强吸收弱反射特性.在实验频率范围内,等离子体阵面对电磁波都有一定的吸收作用,吸收值在9.9~25.6 dB之间,但在不同频段也存在着明显的吸收峰值.同时,虽然等离子体阵面对入射电磁波确有反射,但反射强度非常低,在0~3.5 dB之间.本实验对构建等离子体隐身屏障有借鉴意义.

Abstract: Experiments were carried out to investigate the absorption and reflection of electromagnetic waves (range from 50MHz to 3GHz) by plasma array panels.The results show that plasma has the features of strong absorption and weak reflection on the incident electromagnetic waves.On the scope of experimental frequencies (50 MHz to 3 GHz),plasma array panels absorb all the incident waves more or less with the values between 9.9 and 25.6 dB,but there're several absorption peaks in different frequency bands.Additionally,plasma can reflect electromagnetic waves,but the value is very low,between 0 and 3.5 dB.The results are of great significance to the construction of plasma stealth barriers.
