Abstract
AbstractCompared with devices controlling microwave and visible light, there is a lack of functional devices for terahertz (THz) wave control. Moreover, the available THz elements are usually manufactured with bulk materials, in contrast to the trend of miniaturization and compact device requirements. Here, full control of both phase and amplitude is achieved experimentally and numerically at 0.14 THz, one of the atmospheric windows, by demonstrating the functionalities such as polarization conversion, metalenses and the generation of a non‐diffraction Airy beam. Significantly, the metal structures are fabricated on a flexible substrate with a total thickness of ≈0.063 l via a standard flexible printed circuit technique. Taking into account the considerable manipulation efficiency and cost‐efficient sample fabrication technique, the results show solid advances in the development of metasurfaces as a versatile platform for designing practical functional devices in the THz range.
