Reply To: DGTD band structure calculation

[hamid.h.javadi]

 

I want to run bandstructure calculation of a 1-D array of plasmonic gold nanowires in DGTD.

I modified DGTD example “dgtd_plasmonic_dolmen” to include only one gold wire. I added “periodic” to the “boundary condition” and choose “simulation region” confined to “source_rectangle” (-0.06um to 0.06 um), I get

               period=getperiodicity(“DGTD”);

               ?period;

                            0.06 um as xmin of “simulation region” is forced to zero.

I chose "x: set based on source angle" and changed source angle “theta” from 0 to 10 to 45 degrees. No difference in resonance frequencies (PEC or PMC symmetry) was observed (between different theta runs).

Is this the right approach?
