Optical Transmission Properties of Plasmonic Crystals
Dr. Wan Kuang
In this poster, the optical transmission properties of plasmonic crystals are investigated. These crystals are 150nm Ag films perforated periodically with air holes in a triangular pattern. The optical transmission is measured as a function of incident angle and wavelength for p-polarization. The angle where peak transmission occurs is found to be wavelength dependent in a manner consistent with the Bragg diffraction model. This enhanced transmission is a result of surface plasmon resonance.
