In this paper, a periodic superconducting structure (PSS) with a multiwindow spin Hall effect (SHE) is proposed. Through using the multipeak and angle-sensitive characteristics of the evanescent wave, transmission defects at different angles are achieved for $p$ waves and $s$ waves. Based on this, the multiwindow SHE can be obtained by controlling the number of transmission peaks. Both the horizontal and vertical components possess a considerable displacement. The number of the window is inversely proportional to the value of displacement. The effects of temperature and ordinary dielectric on the two displacements are also discussed. The calculated results show that the temperature has little impact. While the refractive index of ordinary dielectric increases from 1.924 to 2.124, the positions of the two displacements quickly grow from 0° to 80°. Besides, a linear range can be found, and the optimal sensitivity can reach over ${253.9}^\circ \cdot {{\rm{RIU}}^{- 1}}$, which is suitable for detecting tiny changes in the refractive index. Our investigation provides theoretical guidance for obtaining the multiwindow SHE and a refractive index sensor with high precision.

基于渐逝波周期超导结构的多窗口自旋霍尔效应及其应用研究

在本文中，提出了一种具有多窗口自旋霍尔效应 (SHE) 的周期性超导结构 (PSS)。通过利用倏逝波的多峰和角度敏感特性，实现了$p$波和$s$不同角度的传输缺陷波浪。在此基础上，可以通过控制传输峰值的数量来获得多窗口 SHE。水平和垂直分量都具有相当大的位移。窗口的数量与位移值成反比。还讨论了温度和普通电介质对两种位移的影响。计算结果表明，温度影响不大。当普通电介质的折射率从 1.924 增加到 2.124 时，两个位移的位置迅速从 0° 增加到 80°。此外，可以找到一个线性范围，最佳灵敏度可以达到${253.9}^\circ \cdot {{\rm{RIU}}^{- 1}}$，适用于检测折射率的微小变化。我们的研究为获得高精度的多窗口 SHE 和折射率传感器提供了理论指导。
