hey ravil

by changing material we can modulate band gap in photonic crystal structures. modification in holes dimesion (i.e. circular or elliptical) also effect band gap

[Sourabh SahuParticipant]

is it possible to simulate micro toroid and mico ring resonator using OptiFDTD

Hi davcm,

Band gap only changes when you make significant change in hole structures i.e. either increase or decrease dielectric constants of holes. When you increase the dielectric constant propagation vectors in PWE expansion moves down and vice versa.
