Figure 1. Wavefront shaping assisted by a disorder-engineered metasurface.

Figure 1

(a) The system setup consists of two planar components, an SLM and a disorder-engineered metasurface. (b) The disorder-engineered metasurface is implemented by fabricating the nanoposts with varying sizes, which correspond to different phase delays ϕ(x,y) on the metasurface. (c) The wide angular scattering range enables high NA focusing over a wide FOV. (d) The thin, planar nature of the disordered metasurface yields a large memory effect range and also makes the transmission matrix of the metasurface extraordinarily stable. (e) The SLM enables reconfigurable control of the expanded optical space available through the disordered metasurface.
