Query: Spatial adiabatic passage processes in sonic crystals with linear
  defects   We investigate spatial adiabatic passage processes for sound waves
propagation in sonic crystals, consisting of steel cylinders embedded in a
water host medium, that present two linear defects. This work constitutes an
extension of the well-known quantum optical rapid adiabatic passage technique
to the field of sound propagation. Several spatial adiabatic passage devices
are proposed, by appropriately designing the geometry of the two linear defects
along the propagation direction, to work as a coherent multifrequency adiabatic
splitter, a phase difference analyzer and a coherent multifrequency adiabatic
coupler. These devices are robust in front of fluctuations of the geometric
parameter values.
