Bessel beams are generated by the propagation of plane waves along a conical surface. Experimentally such beams exist for a finite distance (near-field) however abruptly transforms into an annular ring (far-field). Here we outline a new optical method which allows a Bessel function to exist in the Far-field as the propagation distance tends to infinity.
