Permittivity of AuAg alloys along with calculations and measurements of the alloyed Fano-resonant structures

Here I present the data corresponding to the manuscript "Low temperature annealing method for fabricating alloy nanostructures and metasurfaces: Unlocking a novel degree of freedom" (arXiv:2105.02461). In this work, I have provided a technique of alloying AuAg at low temperature. Here I present the measured ellipsometric data of the AuAg alloys alloyed at low temperatures and measurements of the single structure AuAg alloyed 4-rod Fano-resonance nanostructures. I have also provided the calculations of the Fano-resonant structures using the permittivity of the Rioux model as well as well as the permittivity obtained from the Rioux model. Each .zip file is associated with a Readme file explaining everything in greater details.
