Abstract
A couplant feeding circuit is provided. The couplant feeding circuit has a first set of walls extending from a bottom surface and a second set of walls extending from the bottom surface and between the first set of walls. A membrane extends between the first and second set of walls such that the first and second set of walls along with the membrane form a couplant cavity. The couplant feeding circuit also has a couplant port disposed in one of the first or second set of walls that allows routing of couplant to the couplant cavity. Moreover, the couplant feeding circuit also has a vacuum port disposed in one of the first or second set of walls that allows removal of at least a portion of the couplant from the couplant cavity. Furthermore, the couplant port and the vacuum port form a closed loop within the couplant feeding circuit.
