利用受单轴横向应力影响而伸长的弹性体的平衡构形，计算了斜入射平面波在弹性体平板上的反射和透射的边值问题的解。当弹性体处于临界应力附近时，发现一个左旋圆偏振的薄反射带淹没在一个较宽的右旋圆偏振反射带中。此外，得到了反射带的变形和带宽的减小。这些带隙特性建议设计一种精细调谐的偏振通用光学滤波器。
Using the equilibrium configuration adopted by a cholesteric elastomer elongated by the influence of a uniaxial transverse stress, the authors calculate the solution of the boundary-value problem for the reflection and transmission of obliquely incident plane waves due to a elastomer slab. The authors find a left-circularly polarized thin reflection band immersed in a wider right-circularly polarized band reflection when the elastomer is under a stress near to the critical value. Also, a deformation of the reflection band and the reduction of its bandwidth were obtained. These band gap features suggest to design a finely tuning polarization-universal optical filter.
