I am currently using a software called "SCOUT" to thin film interference simulation, and I would like to know if there is a better software to do this type of simulations. My goal is to vary the thickness of a thin film in a multilayer, in order to create interference between the various thin films, and then create a specific color. So I want to freely change the thickness and get a graph of reflectance or transmittance corresponding to that change. The software should allow me to put my own materials with the respective reflectance and transmittance properties. I know some softwares, like "zemax" and "lumerical" but there are no videos doing what I intend. Does anyone have suggestions? Thank you!
