Yoseph Bar-Cohen
Yoseph Bar-Cohen is a physicist retiree from the Jet Propulsion Laboratory (JPL). He specialized in electroactive materials and ultrasonic nondestructive evaluation, and was responsible for the JPL's Nondestructive Evaluation and Advance Actuators lab. He was formerly a Group Supervisor and a Senior Research Scientist. Bar-Cohen is a fellow of the International Society for Optical Engineering and the American Society for Nondestructive Testing. Bar-Cohen is a Fellow of the technical societies: The International Society for Optical Engineering, the American Society for Nondestructive Testing, and IAAM. He made two notable discoveries of ultrasonic wave phenomena in composite materials: the polar backscattering and the leaky Lamb waves . He has in 43 registered patents as well as edited and coauthored 12 books, co-authored 460+ publications, and co-chaired 56 international conferences. . Using ultrasonic waves in composite materials, he discovered the polar backscattering and leaky lamb waves phenomena
Bar-Cohen received a M.Sc. in materials science in 1973 and a Ph.D. in physics in 1979, both from the Hebrew University in Jerusalem.
Bar-Cohen started SPIE's Electroactive Polymer Actuators and Devices conference, which he has chaired six times, as well as proposing the Armwrestling Match of EAP Robotic Arm Against Human.
