This contribution explores the design and implementation of metasurfaces capable of manipulating and generating composite vortex beams. By exploiting reflective or transmissive elements, metasurfaces offer unprecedented control over the spatial amplitude and phase distribution of reflected or transmitted fields, enabling the generation of complex vortex structures and the implementation of simple reconfiguration strategies. The study investigates the underlying principles and implementation techniques, demonstrating the efficacy of reflective and transmitting metasurfaces in generating composite vortex beams with tailored properties.
