研究了旋转等离子体超材料的负折射特性。假设等离子体超材料是由等离子体和介质材料周期性地组成。分析结果表明，等离子体密度、填充因子和旋转角对负折射特性有显著影响。有趣的是，当旋转超材料的光轴时，未表现出负折射效应的等离子体超材料将表现出负折射，而当旋转光轴时，表现出负折射效应的等离子体超材料的负折射入射角范围将减小甚至消失。利用等离子体的比旋角和等离子体密度可以获得全角负折射。详细讨论了等离子体密度、等离子体填充因子和旋转角对负折射效应的影响。
The features of negative refraction are investigated by using a rotational plasma metamaterial. It is assumed that the plasma metamaterial is composed of plasma and dielectric material periodically. The analytical results show that the plasma density, plasma filling factor, and rotation angle significantly changed the properties of negative refraction. Interestingly, the plasma metamaterial without exhibiting negative refraction effect will show negative refraction when rotating the optical axis of the metamaterial, while the range of incident angle for negative refraction will be reduced or even disappear for the plasma metamaterial exhibiting negative refraction effect when rotating the optical axis. Moreover, the full-angle negative refraction can be obtained by specific rotation angle and plasma density. The effects of plasma density, plasma filling factor and the rotation angle on the properties of THE negative refraction effect are also explored and discussed in detail.
