Finite-aperture Microwave Bessel Beams with Vortex Twisting, Fracturing, and Dynamic Phase-shift Control

Finite-aperture microwave vortex beams of various structures in the near-, middle-, and far-field propagation zones have been simulated. The decay of external sidelobes leading to the end of non-diffractive propagation within a fraction of the near-field zone is observed. A ring source of the vortex...
