The interplay between light polarization and matter is the basis of many fundamental physical processes and applications. However, the electromagnetic wave nature of light in free space sets a fundamental limit on the three-dimensional polarization orientation of a light beam. Although a high numerical aperture objective can be used to bend the wavefront of… (More)
we proposed a method to generate a versatile localized surface plasmon with the capability of beam steering and shaping by using collinear Kretchmann configuration in conjunction with spatially inhomogeneous polarized beam.
