Surface Plasmons in Light Interaction With Metallic Nanostructures and Applications

In this invited paper, we present the surface plasmons effect as a result of light interaction with metallic nanostructures such as a gold nanosphere or an array of gold nano-slits. Numerical simulation using a finite difference time domain method coupled with Drude model revealed the light enhancement near the gold nanostructures due to the surface plasmon effect. Experimentally, we demonstrated such effect in laser deformation of a polymer shell coated with gold nanospheres. We also employed such enhanced light field for nanoscale lithography.
