论文摘要
负繁殖是由poynting载体成分的局部符号变化产生的一种罕见的响应。我们为使用标量电势的所有不变光束提供了一般的poynting矢量表达，以评估负繁殖的可能性。我们分析了负繁殖与模式混合无关的合理性；我们将韦伯梁研究为特殊情况。对这种负面影响的研究使我们能够在微观操纵和对光学的理解领域发展。讨论了这些光束的应用。
Negative propagation is an uncommon response produced by the local sign change in Poynting vector components. We present a general Poynting vector expression for all invariant beams with cylindrical symmetry using scalar potentials in order to evaluate the possibility of negative propagation. We analyze the plausibility of negative propagation being independent of mode mixing; we study Weber beams as a particular case. The study of this negative effect allow us to advance in the field of micro manipulation and understanding of optical forces. Applications of these beams are discussed.
