Optical Transparent Behaviors of Double Plasmonic Arrays Sandwiched with a Metal Film

Abstract

We propose a high tunable plasmon-induced transparency metal film structure which can be performed by double two-dimensional hexagonal lattice array of plasmonic nanoparticles inserted with a continuous metal film. The structure shows metal transparency in the optical regime. The transparency response in this structure can be efficiently modified by varying the thickness of the metal film, the size of nanoparticles, and the position of the nanoparticles. The structure proposed here may provide a new alternative approach to obtain transparent and highly conducting metal structures with potential applications in optoelectronic integrated circuits, plasmonic filters and transparent conductors.
