Abstract

In this paper, based on phase gradient principle, a multi-function dual-layer reflective metasurface is proposed for linear-to-circular (LTC) polarization conversion, beam control and gain improvement. The rotation of reflected circularly polarized wave is switched by the electric field direction of incident linearly polarized waves. At the same time, the reflective circularly polarized wave emerges anomalous refraction (45.6°). The maximum gain of the reflected wave is increased by 3.6 dB (70%). The measured results and simulation results are in a reasonable agreement. The presented multi-function metasurface may offer unprecedented potentials for real-time, fast polarization conversion and beam control.
