Acoustic channel drop tunneling in a phononic crystal

Résumé

We study both theoretically and experimentally the possibility of resonant tunneling of acoustic waves between two parallel guides created in a phononic crystal composed of steel cylinders in water. In the absolute bandgap of the phononic crystal, ranging from 250 to 325 kHz, a full transmission band exits for propagation inside a straight wave guide. We show that the transfer of a particular wavelength can occur between two parallel wave guides coupled together through an appropriate coupling structure. The latter is composed of isolated cavities interacting with stubs located at the sides of the wave guides.
