Abstract: A transducer device may include an active layer having a proximal surface and a backing layer having a distal side and a proximal side, the distal side being adjacent to the proximal surface. The proximal side may include (1) at least one first reflective surface approximately parallel to the proximal surface and positioned a first distance from the proximal surface, and (2) at least one second reflective surface approximately parallel to the proximal surface and positioned a second distance from the proximal surface, the second distance being different than the first distance.
