Acoustic Supercoupling in a Zero-Compressibility Waveguide

Figure 1

Geometry of the CNZ supercoupling experiment. The geometry under analysis consists of input and output waveguides connected by a much wider intermediate channel with variable length. The output port remains flush with the face of the wooden boundary and moves along with the boundary as L is varied. (Inset bottom): transmission-line model. Inset top-left: photograph of the experimental setup.
