A single-layered metasurface is proposed by Q. Cheng, T. J. Cui, and co-workers to realize broadband diffusion at terahertz frequencies based on the destructive interference from a number of sub-wavelength elements. On page 1405, two kinds of elements are used to achieve full phase range and a linear phase response. The scattered waves can be efficiently manipulated to disperse into nearly all directions, resulting in extremely low back-scattering. The metasurface shows excellent angular independence toward incident waves across a broad spectrum.
