Hi! I have samples of multiple thin films. Thin film of which refractive index needs to be estimated is sandwiched between substrate and capping layer of known refractive indices and extinction co-efficients. I have transmission and reflection spectra of the samples and with the help of these spectra I need to estimate the n, k values for this sandwiched film. I believe there are some non-professional software available which are developed by using matrix formulation and where I can give input of guessed values of n, k and it gives output in the form of transmittance that I can compare with my experimental curve. Do anyone has this type of software available?
