Particle displacement

Is there a formula for determining local particle displacement
caused by ultrasonic vibration in a medium? I would suspect that the
displacement is proportional to the displacement of the
transducer but it should be more difficult to cause cause
displacement in solids than liquids.
Also, are the transverse particle displacements caused by
mode conversion from compression mode to transverse mode of an
amplitude equal to that of the compression mode? Is this
dependent on the incident angle (above or below critical angle)?

Thanks
Ed

Re: Particle displacement cements at mode conversion are a function of the incident angle as you suggest.
