Size effect for plasmon resonance in metallic nanoparticles has been studied by finite element method solution of the Maxwell equations (COMSOL), by the Mie approach and microscopic random phase approximation model. Comparison with Au, Ag nanoparticles experimental data for light extinction in colloidal solutions with different particle sizes is presented for the three types of approach.
