Influences of different types of piezoelectric shunting circuits on band gaps of phononic beam
不同压电分流电路对声子晶体梁带隙的影响

Piezoelectric patches connected with shunting circuits are periodically placed along a base beam,forming a one-dimensional phononic crystal. Different types of shunting circuits will determine the band structure of the beam. Resistive shunting circuits can restrain the beam's modal vibrations to some extent and the band gaps of the beam can be changed by weakening the piezoelectric effect. LC shunting circuits can produce locally resonant gaps induced by LC circuits' electromagnetic oscillations excited by ...
