Abstract
We demonstrate the possibility to efficiently deflect a light beam by varying the refractive index inside resonant contiguous subwavelength slits carved on an opaque metallic substrate in the enhanced transmission regime. The enhanced transmission process combines with the phase mismatch of the surface waves propagating along the metal surface and field localization phenomena to allow controlled transmittance and beam deflection.
