I'm having trouble understanding the difference between normal flux commands (add-flux) and the flux-in-box command. As far as I can tell, they can both be used to compute the flux through a plane or line. From reading archived questions, it seems that flux-in-box is usually used with a fixed frequency source and add-flux flux planes are generally used with a Gaussian pulse. Also, flux-in-box can be used to get the flux at a single time step (which I didn't really get from the reference section).
Mainly, I'm confused on when to apply these different commands. I've been trying to use normal add-flux commands to determine how a photonic crystal structure enhances vertical emission versus that of a homogenous slab, but the results don't seem to be what I intuitively expect, with regards to emission at band gap frequencies or above the cut off frequency, etc. Thank you Rob _______________________________________________ meep-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
