We demonstrate the existence of a class of optical beams where the nonconservative forces can be locally oriented in a direction opposite to the propagation wave vector. Objects placed in the vicinity of these locations will move toward the source of light. The behavior of these negative forces is discussed for the particular case of nondiffracting rotating scale-invariant vector electromagnetic waves.
我们证明了存在一类光束，在这些光束中，非保守力可以在与传播波矢相反的方向上局部定向。放置在这些位置附近的物体将朝着光源移动。对于无衍射旋转标度不变矢量电磁波的特殊情况，讨论了这些负力的行为。
