Tunable multidispersive bands of inductive origin in piezoelectric phononic plates

A variety of multidispersive, localized, or extended in frequency, bands, induced by inductance-based external electric circuits piezoelectric phononic plates, is studied both theoretically and experimentally this work. Their origin, tightly related to an equivalent LC-circuit behavior, analyzed detail their interaction with the Lamb-like guided modes plate also discussed. These easily tuned choice parameters circuitry, lead a non-destructive, real-time control dispersion characteristics these structures. Our device analysis can find application improvement surface acoustic wave components offering additional degrees freedom.
