Claim 10:
11. A method for achieving supercoupling in an acoustic path, comprising:
providing an acoustic path comprising an air-filled channel and a boundary layer comprising a material having a Young's modulus (E) that is about 200 GPa or greater, where the acoustic path has an acoustic input port and at least one acoustic output port;
providing a signal having an impedance at the acoustic input port, where the signal is transmitted through the acoustic path to the at least one acoustic output port;
wherein the total signal at the at least one acoustic output port has an impedance equal to the impedance of the signal at the acoustic input port.
