In this article, we investigate the energy flow redistributions of azimuthally polarized Bessel–Gaussian beams in the focal field by modulating the phase of the phase plate and the topological charge of the phase plate. The results indicate that an increase in phase change parameter will cause the energy flow distribution to shift towards the positive direction of the coordinate axis and result in energy flow separating, while an increase in m will gradually concentrate energy into the center area of the energy flow. The change in phase distribution will affect the shape of energy flow distribution and rotating the phase plate will also bring about changes in the energy flow distribution. These phenomena may contribute to particle capture and transport.
