8. Advances in Electromagnetic Transducers
Electromagnetic transducers have a number of inherent advantages, some of which have been touched on by other speakers. Historically, their major disadvantage has been their high insertion loss. We have undertaken a project which has been designed to explore techniques for optimizing transducer efficiencies and increasing the dynamic response of ultrasonic systems which use electromagnetic transducers. Today, we would like to report the results of that project.
