Abstract
In this thesis we theoretically investigate the surface plasmon resonance in metal nanoparticles. We use the multiple scattering method to simulate the electromagnetc propagation and surface plasmon behaviors in particle systems. By this method, the fundamental resonance modes can be clearly resolved. We consider the permittivity functions obtained from the Drude model, experimental results and modification of the size effect. The simulations show that the surface plasmon resonance is greatly influenced by the particle size and arrangement. The enormous field enhancement due to surface plasmon coupling between particles is reported. The interparticle distance and the wave polarization are responsible for the large field magnitude. Finally, we study the plasmon resonance for chains of particles aligned in the polarization and propagating directions. We show the propagation of electromagnetic energy in the chains. These results may improve the development of plasmonic devices.
