摘要: There has been an interest to understand the trapping performance produced by a laser beam with complex wavefront structure because current methods for calculating force ignore effect of diffraction vectorial electromagnetic wave. In this letter, we present method determining radiation on micro-particle, based theory and Maxwell stress tensor approach. This exact enables one deal not only apodization, phase, polarization structures beams but also spherical aberration in system.
