| 摘 要： | 采用FDTD仿真软件对等离子体反射面天线的近场场强分布及远场辐射方向图进行了研究。由仿真所得的方向图导出了不同等离子体密度下5.8G微波的反射率,结果表明电磁波在等离子体中的穿透深度会对反射率造成影响。研究发现这种影响对于频率较低的电磁波更加明显。

| Abstract: | The plasma reflector antenna's near-field intensity distribution and the far-field radiation patterns were studied by FDTD simulation software.The reflectivity of 5.8GHz microwave in different densities' plasma can be derived from the patterns obtained from the simulation;the results show that the penetration depth in the plasma will affect the reflectivity,and the effect is more significant for a low frequency electromagnetic wave. |
