用简单的公式推导了手性磁化等离子体的特征方程,并详细研究了平行于和垂直于外加磁场的色散关系。利用各本征波的色散关系,探讨了磁化等离子体中手性诱导的负折射,并考察了手性度、外加磁场等参数对负折射的影响。结果表明,手性是在不改变介电常数和磁导率的情况下产生负折射的必要且唯一的因素。增加手性程度和减小外磁场都可以导致更大范围的负折射。计算并讨论了效应的参数依赖性。
Characteristic equations in magnetized plasma with chirality are derived in simple formulations and the dispersion relations for propagation parallel and perpendicular to the external magnetic field are studied in detail. With the help of the dispersion relations of each eigenwave, the author explores chirality-induced negative refraction in magnetized plasma and investigates the effects of parameters (i.e., chirality degree, external magnetic field, etc.) on the negative refraction. The results show that the chirality is the necessary and only one factor which leads to negative refraction without manipulating electrical permittivity and magnetic permeability. Both increasing the degree of chirality and reducing the external magnetic field can result in greater range negative refraction. Parameter dependence of the effects is calculated and discussed.
