Abstract :
Propagation-invariant and rotating vectorial Bessel beams are presented. The beams are achieved through discrete computer-generated space-variant subwavelength gratings. Propagation- invariant, controlled rotation of a propeller-shaped intensity patterns through simple rotation of a polarizer is demonstrated.
