Description: 
We propose an alternative metasurface-based approach for the synthesis of Bessel beam launchers at microwaves/millimeter waves, based on an inward cylindrical traveling wave aperture distribution. Our approach simply allows the outward-to-inward cylindrical feeding wave conversion by metallic dihedrons. Although more involved from the manufacturing viewpoint with respect to single layer devices, it can in principle avoid the computationally-heavy design of holography-based Bessel beam launchers. The preliminary numerical results show the effectiveness of the proposed technique.
