Pang, X. (author), Visser, T.D. (author) The Gouy phase, sometimes called the focal phase anomaly, is the curious effect that in the vicinity of its focus a diffracted field, compared to a non-diffracted, converging spherical wave of the same frequency, undergoes a rapid phase change by an amount of ?. We theoretically investigate the phase behavior and the polarization ellipse of a...
