The acoustic matching structure consists of a thin, substantially planar cavity bounded by a two end walls and a side wall.

The end walls and side wall bound a cavity with diameter approximately equal to half of the wavelength of acoustic waves in the surrounding medium. In operation, a transducing element generates acoustic oscillations in the fluid in the cavity.
