anyone working in the area of graphene plasmonic?
i used comsol RF module to simulate the plasmonic wave propagating on free standing graphene sheet, first i used the 2D mode analysis study to analysis the mode, effective refractive index and propagation constant of a graphene nanoribbon. i got a result which is quite correct compared with the theory. then i build a 3D model and use the bounday mode analysis but the result is not as respected .
who can tell me what is the reason ?
ps: the graphene is simulated as a surface current
