Abstract :
We demonstrate ultrathin THz metamaterials capable of high-efficiency and broadband linear polarization conversion in reflection or transmission. Through the creation of a linear phase gradient, they are further employed in the demonstration of near-perfect anomalous reflection/refraction.
