Abstract:We report an experimental study of the optical transmission of polarized light through subwavelength slit structures in Au films. We investigated the transmission properties by varying the slit number, period, and width. The transmission spectra were strongly depend on the polarization of the incident light. Transmission minima were observed for transverse magnetic (TM) polarization at the wavelength of surface plasmon (SP) resonance at the air-Au interface. We measured the transmission normalized by the slit … Show more
