Hi Now I'm studying plasmonic nanoparticle.
I can get scattering, absorption and electromagnetic field enhancement.
But I wanna get surface charge density from simulation result.
someone said write rho=epsilon0_const(nxemw.Ex+nyemw.Ey+nzemw.Ez) into comsol but actually I'm a beginner at COMSOL. So I cannot get how to do. If that expression is right where should i put that expression? I already put that in variables section but error message is occured they said nx is undefined value. Please explain A to Z for surface charge density plot.
I'll attach some example and my comsol page that I want. additionally my nanoparticle is gold nanocube
Please help me.
