论文摘要
引入手性的自旋选择性反射可以在现实生活中具有许多应用，例如光谱，光学设置，媒体行业等。在本文中，基于反射的跨表面提议在宽带可见和红外（IR）方案中引入巨大的chiroptical效应。此处证明了基本单元的优化和结果也称为纳米结构。所提出的纳米结构的最佳参数的反射率显示了在反射模式下包含多播巨型手势效应。结果表明，该元表面可以引起大型自旋反射系数，而中等手性覆盖宽带波长。可见的和红外政权中的循环二色性显示了其对我们日常生活中许多应用的潜在适用性。这项工作还提供了一种新的方法，可以在宽带波长范围内实现巨大的自旋效果，而损失较低。
The spin-selective reflection to introduce chirality which can have a lot of applications in real life such as spectroscopy, optical setups, media industry etc. In this paper, a reflection based metasurface proposed to introduce the giant chiroptical effects at broadband visible and infrared (IR) regimes. The optimization and results of basic unit also termed as nanostructure are demonstrated here. The reflectance at the optimal parameters for the proposed nanostructure shows the inclusion of multiband giant chiroptical effects in reflection mode. The results show that this metasurface can elicit large spin-selective reflection coefficients with moderate chirality covering the broadband wavelength. The circular dichroism in the visible and IR regime shows its potential applicability for a lot of applications in our daily life. This work also provides a new approach to achieve giant Spin Hall Effect at broadband wavelength ranges with low loss.
