Arbitrary control of terahertz waves remains a significant challenge. On page 1374, B. Jin, W. Liu, T. J. Cui, and co-workers demonstrate a 1-bit coding metasurface with low reflectivity. When a THz pulse is illuminated on this metasurface, the reflection wave can be diverted into various directions, leading to a low reflectivity of less than −10 dB over a wide frequency range. The metasurface, supported by a polyimide layer, is flexible and conforms to curved objects, therefore, it may be applicable to various THz components or devices in communication and imaging systems.
