COMSOL Tutorial : Computing Localized Surface Plasmon Resonance in COMSOL Multiphysics
This video demonstrates how to compute the localized surface plasmon resonance in COMSOL as well as the optical cross section using the RF module. Refractive index data for silver is taken from Johnson and Christy 1972 (refractiveindex.info).
Defined variables listed below;
nrelPoav : nx*emw.relPoavx+ ny*emw.relPoavy+ nz*emw.relPoavz
sigma_sc : intop_surf(nrelPoav) / S_0
sigma_abs : intop_vol(emw.Qh) / S_0
sigma_ext: sigma_sc + sigma_abs
