We have analyzed the propagation of electromagnetic waves impinging obliquely in a hybrid material, made by a cholesteric elastomer slab with spherical metallic inclusions randomly located in the host material. We have carried out an analytical and numerical model which permits us to obtain the reflection and transmission spectra when the system is submitted to a mechanical stress applied transversely to the cholesteric axis. We have demonstrated that for a large interval of angles of incidence, it can be observed a switching behavior from a discriminatory circular filter to a polarization independent device. The sample also exhibits regions of transformation from right to left circularly polarized waves in the reflection spectra, which are intercalated with zones of similar transmission of both circularly polarized waves.

通过横向拉伸复合胆甾型弹性体的多向转换行为

我们已经分析了电磁波在杂化材料中的倾斜传播，杂化材料是由胆甾型弹性体平板制成的，球形金属夹杂物随机位于主体材料中。我们执行了一个解析和数值模型，当系统承受横向于胆甾轴施加的机械应力时，该模型可使我们获得反射光谱和透射光谱。我们已经证明，对于大的入射角间隔，可以观察到从鉴别性圆形滤波器到偏振无关设备的切换行为。样品在反射光谱中还显示出从右圆偏振波到左圆偏振波的转换区域，该区域插入了两个圆偏振波具有相似透射率的区域。
