An ultrathin free-standing metasurface is proposed to bend the normally incident terahertz wave to an anomalous direction, or to focus plane wave to a point, with high efficiency. The flexibility and endurable nature of the proposed transmitarray make it a promising candidate for various THz applications such as time-domain system or THz imaging devices.
