Investigations into Focused Acoustic Transducers Using Domain Inverted Materials
Abstract
This report results from a contract tasking Sensormetrics as follows: The contractor will develop and demonstrate an acoustic transducer, approximately 1 centimeter and 0.5 centimeter wide. The transducer will operate at a frequency between 200 and 400 MHz directing the acoustic beam by means of a technique equivalent to a fresnel zone plate into a line focus at a nominal distance 0.5 cm from the transducer and lying at an angle of 3 degrees to the plane of the transducer. The primary objective is the production and demonstration of a device in which a domain inverted acoustic transducer is bonded to a suitable substrate used to produce an intense acoustic field in the form approximating to a line focus, and to facilitate the attachment of an optical fiber at this position.
