A computational comparative research is performed to investigate the possibility of optical trapping of a dielectric microcylinder with a circular or elliptical cross section, the diameter of which is comparable to the wavelength of light, when it is placed near the waist of a nonparaxial Gaussian beam or in the focal region of a “sharply” focused Gaussian beam and a plane wave (ratio of lens diameter to focal distance ranged from 0.85 to 1.27).
