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) \(b=5\text{ nm}\)
