Bio

Dr. Meyer is a Senior Research Associate at the Applied Research Laboratory. He is currently the head of the Materials and Device Development Department and the Transducer and Arrays Department, which are part of the SONAR Research and Development Division.  In addition to these roles, Dr. Meyer is also an Associate Professor of Materials Science and Engineering and an Associate Professor of Acoustics.  He joined the Applied Research Laboratory full time in November of 2000.  His undergraduate degree was completed in 1993 in Ceramic Science and Engineering within the Materials Science and Engineering Department at Penn State.  A Masters degree was conferred in 1995 in the Materials program at the Materials Research Laboratory under the direction of Dr. Thomas Shrout. He completed his Ph.D. in October 1998 with the development of high frequency 1-3 composite medical imaging transducers. After graduation, he studied one year as a post-doctoral scholar under the supervision of Dr. Robert E. Newnham, before being promoted to Research Associate at the Materials Research Laboratory. His research interests include ceramic processing, development of undersea and medical sonic and ultrasonic devices and composites materials for actuators and transducers.  He was the recipient of the 2003 Office of Naval Research Young Investigator Award for the study of high power piezoelectric materials.

Research

The SONAR Research and Development Division is responsible for the design, fabrication and testing of advanced acoustic systems for Naval and commercial applications.  The Materials and Devices Department within this division is responsible for the research and development of new active materials and their integration into transducers to advance the state-of-the-art for acoustic projectors and receivers.  The department is actively developing transducers based on traditional piezoceramics, relaxor-based single crystal piezoelectrics, textured piezoceramics, and magnetostrictive materials.  Electromechanical characterization of these materials focus on effects associated with high fields, temperature, and high dynamic stress or strain.  Integration of new active materials into devices starts with performance prediction.  The department utilizes iterative and non-linear finite element analysis for high fidelity performance estimation.  Promising designs are then fabricated with complete engineering drawing packages, advanced tooling and modern facilities.  A 60,000 gallon anechoic test pool is used to characterize and validate in-water acoustic performance.  Long term reliability of new transducer designs or designs incorporating new active materials is also being studied.  Successful device designs are transitioned to the Transducers and Arrays department for incorporation into sonar systems that advance the technology readiness level.  The SONAR Research and Development Division has been very successful in transitioning systems into the Navy and into commercial applications and fast tracking new technology.
