Abstract
Apparatus and techniques are described, such as for obtaining information indicative of an acoustic characteristic of a formation, including using a transducer assembly, comprising a base plate, a first piezoelectric slab and a second piezoelectric slab. The base plate includes a first region extending axially in a first direction beyond the first and second piezoelectric slabs along a specified axis of the base plate and a second region extending axially in a second direction, opposite the first direction, beyond the first and second piezoelectric slabs. In various examples, a length of the first region along the specified axis is different than a length of the second region to provide an asymmetric configuration. In various examples, an anchoring element is mechanically coupled to the base plate at a location corresponding to a node location of a specified acoustic vibration mode.
