研究了由手征无源超材料芯层和非手性包层构成的手征无源光纤中的导模和面模。推导了手征光纤中导模和面模的色散方程及其截止频率。给出了波导模和表面模的色散曲线，并详细讨论了手征参数对色散曲线的影响。发现了一些新的传播特性。
Guided and surface modes in the chiral nihility fiber consisting of a chiral nihility metamaterial core with an achiral cladding have been investigated. The dispersion equations of guided and surface modes in the chiral nihility fiber and their cutoff frequencies are derived. Dispersion curves of guided and surface modes are presented and the effect of chirality parameter on dispersion curves is discussed in detail. Some novel propagation characteristics are found.
