Claim 0:
1. A supercoupling waveguide apparatus, comprising:
an acoustic input port having an input cross-sectional area, where the acoustic input port is adapted for receiving an acoustic signal having an impedance;
an acoustic output port having an output cross-sectional area, wherein the acoustic output port is adapted for transmitting the acoustic signal; and
an acoustic path extending from the acoustic input port to the acoustic output port, the acoustic path having a variable length and a path cross-sectional area that is greater than the input cross-sectional area;
wherein the input and output cross-sectional areas are equal, and the impedance of the acoustic signal at the acoustic input port matches the impedance of the acoustic signal transmitted by the acoustic output port.
