Theoretical study of surface plasmons with phase singularities generated by evanescent bessel beams
We give details about how a surface plasmons with phase singularities can be produced when a Bessel beam light is totally reflected internally at the planar surface of a dielectric on which an infinitesimally thin film has been deposited. The characteristic property of such a light is the exponentia...
