Transverse intensity at the tight focus of a second-order cylindrical vector beam

Transverse intensity at the tight focus of a second-order cylindrical vector beam

In this paper, an effect of a reverse energy flow at the focus of a second-order cylindrical vector beam which passed through amplitude zone plate was investigated with a scanning near-field optical microscope. A comparison of the intensity distribution detected with a pyramidal metallized cantileve...
