N2 - Dual-band metasurface with high efficiency is highly desired for the electromagnetic integrated system. In this paper, a dual-band transmissive meta-atom is proposed to work at cross-polarized mode for the circularly polarized incidence. The meta-atom could achieve a 360° phase coverage with conversion efficiencies better than 70% at two frequencies of X-band simultaneously. As a proof of concept demonstration, a dual-band deflector based on metasurface is designed to deflect the incident wave to the anomalous directions with arbitrary deflection angles. The simulated results show a good expected performance, which could pave the way towards high-efficiency integrated components.
