[Invited] Tunability of electrically controlled piezoelectric phononic crystals

Résumé

Two devices based on Phononic Crystals (PCs) made of piezoelectric materials are studied: (1) a stack of piezoelectric rods or plates, poled along their thickness, (2) a piezoelectric plate, poled along its thickness, covered by periodic arrays of electrodes on its two faces. These devices exhibit Bragg gaps that may be tuned by changing the electrical boundary conditions on the periodically placed electrodes.
