What is calcback?

A tool to calculate the refractive indices of a layer, by using the ellipsometric parameters Delta and Psi

Input should be a .csv file containing the following data:

wavelenght,psi,delta

You can use the “300nmSiO2.csv” as an example file, plotted it looks like this (Delta might need to get multiplied by -1)

Work in Progress:

  • [ ] check the formulas, get the right results (at first just for SiO2, with just real n_L)
  • [ ] Use complex refractive index, not just real(n_L)
  • [ ] Use different resolutions of n_L, to minimize ammount of calculations
  • [ ] add concurrency (for each lambda, maybe each calc_ho())
  • [ ] Output (lambda, n, k) into a .csv

The Goal:

Get a programm to calculate refractive indices for different simulated layers (my python script) made of multiple dielectric/metal periods (eg. 10 times 5nm Ag + 5nm SiO2).
