Summary:

Study of surface plasmnon polariton (SPP) effect is a fundamental scientific cross-disciplinary research area with academic importance and critical application potential. We discuss methods for the manipulation of light and plasmonic properties with nanostructures. With a plasmonic lens, an incident light can be focused by the lens with its width smaller than the limited value in the intermediate zone. This makes the plasmonic lens superior to many critical applications, such as advanced photolithography, imaging, and bio-molecular manipulation. We propose different plasmonic nanostructures to allow the light of red, green, and blue, respectively, to pass through. This can replace conventional optical filters, which is preliminarily verified by one of the primary semiconductor companies in the world. To increase the transmission efficiency, we study the cascade/hybridization effect of SPPs.
