用简化方法推导了电磁波在手征等离子体中传播的色散关系，并进行了详细研究。借助于各本征波的色散关系，我们探讨了手征等离子体如何呈现负折射，并研究了负折射的频率范围。结果表明，手征性可以在等离子体中产生负折射。此外，手征度和外磁场对手征等离子体中负折射的临界频率和频率带宽都有显著影响。的影响的参数依赖性进行了计算和讨论。
The dispersion relations for electromagnetic wave propagation in chiral plasmas are derived using a simplified method and investigated in detail. With the help of the dispersion relations for each eignwave, we explore how the chiral plasmas exhibit negative refraction and investigate the frequency region for negative refraction. The results show that chirality can induce negative refraction in plasmas. Moreover, both the degree of chirality and the external magnetic field have a significant effect on the critical frequency and the bandwidth of the frequency for negative refraction in chiral plasmas. The parameter dependence of the effects is calculated and discussed.
