Sharper Focal Spot for a Radially Polarized Beam Using Ring Aperture with Phase Jump
We study analytically and numerically in which way the width of ring aperture containing a phase jump affects the size and intensity of the focal spot generated with a radially polarized beam. It is shown that by means of destructive interference of beams coming from the different-phase rings it bec...
