Every program does the “forward problem” (given a material configuration, compute the optical properties), but only the programs marked RP also do the “reverse problem” out-of-the-box (given optical measurement data, guess the materials and thicknesses). Opt. These details are available in the above paper. Contact your librarian or system administrator In just one click, we measure thin-film thickness by analyzing how the film reflects light. (24 Hr.
