چکیده انگلیسی
A simple method is proposed to manipulate the transverse energy flow in the focal plane of a tightly focused azimuthally polarized beam. Using the Richards-Wolf formulas, we obtain explicit expressions for all components of the electromagnetic field and the Poynting vector near focus of the tightly focused input field with azimuthal polarization and optical vortex. Further, the redistributions of the transverse energy flow by designing phase masks, including traditional and annular vortex phase masks are explored. Transverse energy flow in the shape of a regular polygon is achieved. As a result, transport absorptive particles can be transported along more flexible paths, which might be help in optical tweezers manipulations.
