FDTD COMSOL HOW TO
The crucial role of the Lorentz friction in the size effect of plasmon resonance in large (e.g., 20–60 nm for Au in vacuum) metallic nanoparticles is evidenced. Tutorial on how to simulate optomechanical coupling in photonic crystal cavities in COMSOL.This content is presented at FEM workshop organized by EPFL in OMT. Comparison with experimental data for light extinction in Au and Ag nano-particle colloidal solutions with different particle sizes is presented. The numerical approach is by the finite element method solution of Maxwell equations for incident planar wave in spherical (also nano-rod, spheroid) geometry upon the system COMSOL and Mie treatment, supplemented with phenomenologically modeled dielectric function of metallic nano-particle. The developed microscopic approach is the quantum random phase approximation model of plasmons in metallic nano-particles including plasmon damping by electron scattering and by radiative losses (i.e., by the so-called Lorentz friction). Contact RSoft Sales for licensing policies regarding this feature.We investigate metal nano-particle size influence on plasmon resonance within theoretical and numerical approaches and compare results with available experimental data in order to improve resolution of optical identification of metallic nano-particle size and shape. Increased performance through parallel processing via multi-CPU/core machines and/or clustering across a network of computers.
