Hello.
I'm also trying to simulate a time dependent structure, but I'm not clear
how to right down the appropriate .ctl file.
It is not clear to me who to define a new structure and initiating it using
(init-structure) and where/when to put the
meep-field-phase-in-material statement.
In addition when I added the following line in my file :
"(meep-field-phase-in-material fields structure 20)"
I got the following in the output : "ERROR: Unbound variable:
meep-field-phase-in-material"
Could someone help with an example and /or detailed explanation?
Thanks in Advance,
Michael Shlafman.
