An efficient approach to generate microwave vector‐vortex fields based on metasurface

This study presents a simple but efficient approach to generate microwave vector-vortex beams based on the metasurface composed of quasi-periodic aperture-coupled patch elements. We demonstrate that the vector-vortex field with or without spiral phase can be achieved by changing the polarization of incident wave. Moreover, the spiral phase and/or polarization angle of produced vector-vortex beams can be manipulated by tuning the topological charge τ. Results obtained using the commercial software CST Microwave Studio 2012 are presented to verify our methodology. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1708–1713, 2015
