    • Here is the code that implements the argument principle method. It was written under Mathematica 6. Might need to be modified to work under newer versions.
    • I also have the Mathematica sheets for the implementation of mode matching. I did not have the time to add more comments to them, if you'd like to take a look at those please let me know, I'll be much more motivated to put them online then.

    • Here is the finite difference frequency domain code used in the simulations of the paper. There are a fair number of lines of comments in the code, but I did not have the time to go over and describe in detail how different sections (C++ for number crunching, Matlab for data analysis, Mathematica for fitting multi-pole Drude parameters) talk to each other. Email me if you would like to learn more about the code.
