摘要：

An anomaly in the refractive index is observed in the cubic liquid-crystalline blue phases (BP's) I and II of several cholesteric-nematic mixtures in the vicinity of optical Bragg reflection. Because the reflection wavelength is of the order of the BP lattice constant, this phenomenon can be explained by spatial dispersion of the dielectric tensor.
