Bound states in continuum in acoustoelastic coupling: physical phenomenon for vibration focusing and energy storage
"Interplay of sound and elasticity... shaker induced vibrating elastic bar, air injection predetermined location engendered coupling between sound and elasticity... reflection progressive elastic wave reverted back along direction came from indefinitely confined... acoustoelastic coupling expanded to vibration focusing and energy storage... filters capable of selectively isolating specific frequencies or the advancement of energy harvesting methodologies that convert kinetic energy into electric energy"
