In this study, elastic wave propagation through a layered phononic crystal made of finite number of unit-cells composed of four elastic/piezoelectric layers and surface electrodes connected by an electrical circuit with a capacitor is considered. The numerical investigation based on the transfer matrix method of the influence of the condenser capacitance on the stop-bands is provided. Some critical values of capacitance providing stop-band transformation into pass-bands are revealed.
