I used Ardavan Oskooi sample input file to form a moving current source
to generate Cerenkov radiation in photonic crystal lattice. The problem
is I am really struggling with Scheme syntax. I am trying to get the
frequencies of the emitted Hz radiation. So I am trying to use the
harminv step-function to find the frequencies. So far nothing is coming
out. However, when I combine to png files, I can see the Hz radiation
propagating.
Is this the way to get the frequencies of the emitted radiation or is
there a better way?
Any help will be appreciated.
