2D Simulation of Surface Plasmon Resonance

摘要：

In the paper,interactions of an electromagnetic wave with a metallic nanoparticle in the optical range for a two-dimensional TM mode (p-polarization) are investigated by a set of new surface integral equations. A critical case of triangular silver is studied by the new integral equations to exhibit a strong local enhancement of the electric field at the sharp edges; the amplification of silver is around 300,which is much stronger than a dielectric nanoparticle. In addition, the surface plasmon resonance (SPR) in elliptical silver is demonstrated, and the results indicate the red shift of SPR can be caused by increasing the aspect ratio of the particle and the permittivity of the host.
