Engineering Fano-resonant hybrid metastructures with ultra-high sensing performances

Here the data related to our recent work that uses metasurfaces designed on metamaterials to excite Fano resonances and Rabi Split analogue modes for sensing. In this repository the following data are available: The Reflectance, Transmittance and Absorbance (1-T-R) evaluated over all the diffraction angles (from 0° to 89°) for the proposed structure (ring + cross) and the other tested structures, available in the .mat file. The .m file to repeat all the simulations are available in main folder. The available Matlab codes allow reproducing numerical simulations using Reticolo (RCWA) as the main framework to do the computation. Use "getrefractiveindex.m" to interpolate refractive index on finest wavelength range. Please, note that according to the uploaded codes this function have to be in the same folder of the loaded refractive indices. You can use the function "textprogressbar.m" to get a progress bar in real time to know the status of the current simulation. Please, note that this function have to stay in the "/RETICOLO V8/reticolo_allege" folder. One of the available Matlab code allows displaying the electric and magnetic field evaluated in the structure section or on the top view. The sensing test performed for the reported structures using different surrounding medium, for this purpose it is possible to use the codes that allow studying the parameters variation, the incident angle variation or just a single run changing the refractive index of the surrounding medium. The proposed code works using the Reticolo main code. To download it please visit the following link https://www.lp2n.institutoptique.fr/light-complex-nanostructures or using Zenodo https://zenodo.org/record/5905381#.Y8rvbC9abpA Once Reticolo has been downloaded copy and paste its path in the proposed Matlab code for Fano resonances on ENZ cavities as reported in the example codes. In this repository you will find the refractive indices that have been used.本数据集关联本团队近期一项研究工作，该研究利用超材料（metamaterials）基底设计的超表面（metasurfaces）激发法诺共振（Fano resonances）与拉比分裂类比模式，用于传感应用。 本仓库提供如下数据： 针对所提出的环+十字结构及其他测试结构，在全衍射角（0°至89°）范围内计算得到的反射率、透射率与吸光度（1-T-R），相关数据存储于.mat格式文件中。 主文件夹中提供了可复现全部仿真过程的.m格式Matlab代码。本套代码以Reticolo (RCWA)作为核心计算框架，实现数值仿真的复现。 使用`getrefractiveindex.m`可在更精细的波长范围内插值得到折射率。请注意，根据上传的代码要求，该函数需与加载的折射率数据处于同一文件夹下。 可使用`textprogressbar.m`函数获取实时进度条，以监控当前仿真任务的运行状态。请注意，该函数需放置于`/RETICOLO V8/reticolo_allege`文件夹内。 其中一套Matlab代码可用于可视化结构截面或俯视图中的电场与磁场分布。 针对所报道的结构，本研究开展了不同周围介质环境下的传感测试。相关功能可通过下述代码实现：用于研究参数变化、入射角变化，或仅通过修改周围介质折射率进行单次仿真运行。 本套代码需依托Reticolo主程序运行。如需下载Reticolo，请访问以下链接：https://www.lp2n.institutoptique.fr/light-complex-nanostructures 或通过Zenodo平台获取：https://zenodo.org/record/5905381#.Y8rvbC9abpA 下载完成Reticolo后，请将其路径复制粘贴至本仓库中针对ENZ腔的法诺共振Matlab代码内，具体可参考示例代码。 本仓库中包含本研究使用的各类折射率数据。
