From: Anomalous diffraction of matter waves with minimal quantum metasurfaces
Percentage of anomalous diffraction of optimal designs for various cavities materials (horizontal axis) and various background hosts (vertical axis). The media have been sorted with increasing potential energy: larger potential, larger serial number (s/n). Designs supporting only two diffracted orders (\(u=0,-1\)) maximizing (a), (c) anomalous reflection probability \(\rho _{-1}\), (b), (d) anomalous transmission probability \(\tau _{-1}\), with: (a), (b) \(b=2.5\text{ nm}\) and (c), (d) \(b=5\text{ nm}\)
