Reviewer 2 Report
In this manuscript, the authors investigated the longitudinal inverse energy flow of vector Lissajous beams in the focal plane. The possibility of forming inverse energy flow profiles can be designed intentionally by manipulating the polarization indices, under which the formation of not only separate isolated regions with a reverse energy flow but also entire directions are provided. This study enables the detailed inverse energy flow analysis of the vector Lissajous beams, which helps the design optimization process prior to application. So, I recommend it for publication. I suggest the authors address the following comments before accepting this manuscript.
- Line 274, “It can be seen that there are infinite through…”. What does ‘infinite’ mean in this sentence? Is the region of inverse energy flow? Please make it clear.
- In table 3, in the cases of q=4 and q=5, the inverse real energy flow seems to be discontinuous for q=3 while be continuous for q=5. Please give the reasonable explanation.
- Please explain the physical meaning of the directions of the arrows in tables.

Reviewer 3 Report
The authors of this paper studied the tightly focusing properties of a novel class of generalized cylindrical vector beams, named vector Lissajous beams. In particular, they studied the negative flow of energy in the focal plane induced by the Lissajous type polarization state of the input beam. They showed both analytically and numerically that by controlling the polarization indices and the phase difference between x- and y-polarization components, the regions of negative energy flow can be modulated. The results are interesting and could find uses in the manipulation of optical pulling forces. I recommend this work accept as is.
