Abstract:
The redistribution of transversal energy flow and polarization in the focal field are represented by obstructing an azimuthally polarized beam with rotationally symmetric sector-shaped obstacles. Several energy flow rings that can finally transport the absorptive particles into fixed locations are formed in the focal plane. Furthermore, the local polarization state of the focal field is also modified by use of the rotationally symmetric obstacles. This kind of energy flow may have wide applications in optical trapping and manipulation.
