Time-domain observations of fast and slow ultrasonic group velocities in microsphere suspensions
In dispersive media, propagating wave packets can exhibit abnormal group velocities that differ substantially from the phase velocity of the dominant mode comprising the pulse. Recently, both arbitrarily large and negative acoustic group velocities were shown to exist in an aqueous suspension of pol...
