  • Abstract
    We experimentally demonstrated a wide-angle unidirectional excitation of surface plasmon modes. Employing the plasmonic critical angle phenomenon in conjunction with the grating effect, a wide incident angular full-width-half-maximum (AFWHM=25°) with high unidirectionality of extinction ratios better than 10dB was realized.
