摘要：Waves of light, just like sound waves or water waves, consists of sines and cosines. But if we take a closer look, this is not the whole story. If we zoom in at length scales that are smaller than the wavelength, we find that there are special points, called singular points, where the light behaves strangely. One example of such points are tiny optical tornadoes. But also the polarization of the light can have a strange behavior at certain points. New research has shown how these different points are related, and how we can create them or make them disappear. This talk is aimed at graduate students. It is suitable for everyone who has taken a course in electromagnetic fields. Some of the results that I will discuss have been published in: X. Pang, G. Gbur and T.D. Visser "Cycle of phase, coherence and polarization singularities in Young's three-pinhole experiment" Optics Express, vol. 23, pp. 34093-34108 (2015).
