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

<p>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.</p> <p>&nbsp;</p> <p>In this repository the following data are available:</p> <ul> <li>The Reflectance, Transmittance and Absorbance (1-T-R) evaluated over all the diffraction angles (from 0&deg; to&nbsp;89&deg;) for the proposed structure (ring + cross) and the other tested structures, available in the .mat file.</li> <li>The .m file to repeat all the simulations are available in main folder. The available&nbsp;Matlab codes allow&nbsp;reproducing&nbsp;numerical simulations using Reticolo (RCWA) as the main framework to do the computation.</li> <li>Use &quot;getrefractiveindex.m&quot; to interpolate refractive index on finest wavelength&nbsp;range. Please, note that according to the uploaded codes this function have to be in the same folder of the loaded refractive indices.&nbsp;</li> <li>You can use the function &quot;textprogressbar.m&quot; 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 &quot;/RETICOLO V8/reticolo_allege&quot;&nbsp;folder.&nbsp;</li> <li>One of the available Matlab code allows displaying&nbsp;the electric and magnetic field&nbsp;evaluated in the structure section or on the top view.&nbsp;</li> <li>The sensing test performed for the reported structures using&nbsp;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.&nbsp;</li> </ul> <p>The proposed code works using the Reticolo main code. To download it please visit the following link&nbsp;<a href="https://www.lp2n.institutoptique.fr/light-complex-nanostructures">https://www.lp2n.institutoptique.fr/light-complex-nanostructures</a>&nbsp;or using Zenodo&nbsp;<a href="https://zenodo.org/record/5905381#.Y8rvbC9abpA">https://zenodo.org/record/5905381#.Y8rvbC9abpA</a></p> <p>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.</p> <p>In this repository you will find the refractive indices that have been used.</p>
