Abstract
In this paper, a novel method for the manipulation of linearly polarized (LP) electromagnetic waves using Pancharatnam–Berry phase is proposed. By combining polarization synthesis and aperture phase distributions, the polarization angle and wavefront of an LP wave can be arbitrarily manipulated. Four metasurfaces were designed and fabricated to generate pencil, vortex, and Bessel beams with different polarization angels, respectively. Simulation and measurement results consist well and demonstrate the proposed method in both polarization and wavefront manipulation.
