非傍轴突变自聚焦光束
Nonparaxial abruptly autofocusing beams
摘要：
我们研究了具有预先设计轨迹的非傍轴自聚焦光束。我们考虑的情况下，线偏振的电光束，并检查其聚焦特性，如对比度，光束宽度，和数值孔径。这样的光束与较大的强度对比度相关联，可以聚焦在较小的距离处，并且与近轴状态相比具有较小的光斑尺寸。
英文摘要：
We study nonparaxial autofocusing beams with pre-engineered trajectories. We consider the case of linearly polarized electric optical beams and examine their focusing properties such as contrast, beam width, and numerical aperture. Such beams are associated with larger intensity contrasts, can focus at smaller distances, and have smaller spot sizes as compared to the paraxial regime.
