Hello
to plot the dispersion diagram you need the following boundaries conditions:
±x periodic boundaries
±y periodic boundairies
± electric boundaries
then always in the boundaries conditions, if you have selected periodic boundaries, you will have a new slot : "Phase Shift/Scan Angles"
In the text box x and y: you put a variable like phase which inits to 0.
Then you lauch the eigen solver.
Parameter sweep
New Sequence
Choose the phase variable and choose sweep from 0 to 180.
Add watch: Frequency of Mode 1 & Frequency of Mode 2.
Now start and it will plot your absorption diagram.
If you have a sievenpiper structure upload it and iI will configure it.
regards
piboo
