Hi guys,
I am trying to simulate whispering gallery modes in a plasmonic hybrid resonator. I am using a 2D axisymmetric wave optics module. I need to compute the mode volume (as given in eq. 18 of the attached paper) for which I need to perform volume integration on particular domains. When I am trying to compute the "volume integration" from "derived values" I do not get any domain selection option and thus the evaluation does not fetch any result. Please help.
Thanks in advance. Best regards Shubhayan
