| 摘 要： | 通过磁约束线形空心阴极放电的方式生成了大面积高密度的等离子体片,并分别在4.5 GHz、5 GHz和6 GHz频率研究了其对角椎天线发射出的微波所产生的影响.实验所得的磁化等离子体片对所选频率的微波能有明显的衰减作用,而衰减作用在不同方向有很大差异.

| Abstract: | We produced a large plasma sheet of high density by the discharge of a linear hollow cathode in a homogeneous magnetic field,and studied its impact on the microwaves generated by a gain horn antenna at the frequency of 4.5 GHz,5 GHz and 6 GHz. The plasma can easily weaken the energy of microwave,but the attenuation of microwave varies greatly in different directions. |
