Supercoupling waveguides are provided in which acoustic impedance at an acoustic input port matches the acoustic impedance at an acoustic output port, where the acoustic path extending from the acoustic input port to the acoustic output port has a variable length. The supercoupling waveguides may be used in methods of sensing and measuring, and may be incorporated into sensors.

Supercoupling waveguides, and methods for making and using same

Supercoupling power dividers are provided, in which acoustic impedance at an acoustic input port matches the combined acoustic impedance at two or more acoustic output ports, and the phase of the input signal matches the combined phases of the two or more acoustic output ports. Methods for achieving impedance matching using a uniform-phase acoustic power divider are also provided. The devices and methods achieve acoustic supercoupling without requiring embedded membranes or resonators.
