Abstract
A novel dual-band meta-atom for the Pancharatnam-Berry metasurface is proposed, which can realize simultaneous phase and amplitude modulations at two terahertz frequencies. Based on the meta-atom, a dual-band Airy beam generator and a dual-band autofocusing Airy beam generator are numerically demonstrated. The full wave simulation results agree well with the numerical calculation results, and both results satisfy the designed goals.
