Abstract: | ![]() Plasmonics has become a new research hot spot in recent years.The collective oscillation of electrons at the dielectric and metal interface is a kind of electromagnetic excitation known as a surface plasmon polariton(SPP).Because of their specific coupling and propagation properties,the design and application of SPP-based devices have become a foremost direction in nano-optics research.In this article we report our investigations on the fabrication of SPP nanostructures,and the characterization of the SPP f... |
