Directional Selectivity through the Subwavelength Slit in Metallic Gratings
CLEO:2011 - Laser Applications to Photonic Applications
An approach for obtaining strong directional selectivity through a single subwavelength slit in non-symmetric metallic gratings is shown theoretically and experimentally. Directionality effect originates from the different resonance frequencies of two interfaces.doi:10.1364/cleo_at.2011.jtui67 fatcat:bgd2pfhvhbgmjdkglkfevbvwqy
