Query: Full transmission and reflection of waves propagating through a maze of
  disorder   Thirty years ago, theorists showed that a properly designed combination of
incident waves could be fully transmitted through (or reflected by) a
disordered medium, based on the existence of propagation channels which are
essentially either closed or open (bimodal law). In this Letter, we study
elastic waves in a disordered waveguide and present direct experimental
evidence of the bimodal law. Full transmission and reflection are achieved. The
wave field is monitored by laser interferometry and highlights the interference
effects that take place within the scattering medium.
