Hi, I am a new player in Meep. Recently I try to simulate the transmission of silicon nitride directional coupler. The waveguide core material I use is silicon nitride. The waveguide cladding material is silicon dioxide. I have checked the directional coupler example( https://meep.readthedocs.io/en/latest/Python_Tutorials/GDSII_Import/#s-parameters-of-a-directional-coupler). I think the background refractive index is air(n=1) in that example. I am wondering if it is possible to set the background refractive index as the refractive index of silicon dioxide. Thanks in advance.
Regards, Siwei
