I had simulated a graphene nanostripe based on surface conductivity mode and volumetric permittivity mode of graphene, respectively. Results showed that resonance wavelength of graphene nanostripe obtained by surface conductivity was about 1500nm larger than that obtained by volumetric permittivity of graphene. Why there are so big difference?
My simulation file:surface conductivity mode of graphene.fsp (252.4 KB) and volumetric permittivity mode of graphene.fsp (250.2 KB)
The transmission spectra are as follows:
Thanks for any help.
