Tunable bandpass filters using a defective phononic crystal shunted to synthetic negative capacitance for longitudinal waves

Journal of Applied Physics, Journal Year: 2024, Volume and Issue: 135(16)

Published: April 22, 2024

This study illustrates the successful achievement of tunable defect bands in one-dimensional defective phononic crystals (PnCs) through incorporation piezoelectric defects with synthetic negative capacitances (SNCs) for first time. The efficacy SNCs creating bandpass filters across a broad frequency range is thoroughly examined using proposed analytical and numerical models. A newly developed electroelastically coupled transfer matrix that incorporates presented, considering either series or parallel connection between bimorph elements. Defect band transmittance analyses are conducted S-parameter methods. Two key findings emerge from this investigation. First, when total equivalent capacitance elements SNC becomes zero, representing point-symmetric defect-mode shape can be customized throughout entire bandgap. Second, constant value, resembling short-circuit conditions, highlights remarkable ability to tune without energy dissipation, paving way fully filters. To propel research forward, future investigations could explore expanding design space double defects, adopting enhanced modeling techniques account lateral shear effects, developing control algorithm automatic optimization values actively filters, incorporating artificial intelligence into methods electrical connections.
