Adam Isom:
As an addendum to my earlier post, here is a link to some C++ source code I'm trying to use. Even though the computation prints out results for a number of frequencies, I'm looking specifically at the result for 1.81 which should correspond to 45 degrees and 550nm light with the k-value I have chosen. I expect 11% but get around 31%.

    Hello everyone,

    I am trying to compute reflection coefficients for a very simple
    scenario using Meep: plane wave source and a single, free thin
    film.  My original setup used a 2D grid with PML along all
    boundaries and a plane source across the top of the grid, with the
film at the bottom (I set eps to be the IOR squared).

Did you visualize the fields? I doubt that you actually have the plane wave source, because it is set like a point source.

WBR,
Shawkat
