Generation of Free-Space Cylindrical Bessel Beams of Arbitrary Integer/Non-Integer Orders
We present a method to generate arbitrary free-space Bessel beams and particularly Non-Integer Cylindrical-Vectorial Bessel Beams (NI-CV-BBs). This method follows from a novel and insightful mathematical representation of NI-CV-BBs. It consists in distributing sources with prescribed conical angular spectrum and azimuthal phase distribution along a circle perpendicular to the axis of the desired beam. This construction is numerically demonstrated and we shall present at the conference an experimental realization of it in the form of a pair of cascaded inhomogeneous wave-plate metasurfaces.
