Dear all my friends and professors

I want to develop an optimization tool in excel software for my research work in optical thin film coatings for single-layer analysis in sputtering or electron beam evaporation.

Basically, software like optilayer, macloed, filmstar all were developed this tool by naming it as re-optimization software.

As for the common research scholars its a problem to purchase the software of higher price. to help the scholars in their research i want to develop an optimization tool for the layer analysis.

Kindly guide me in which way I have to proceed to develop such a re-optimization tool for reducing the coating layers in the hit and trial method by this development.

Thanking you.
