![]() ![]() ![]() Matching the acoustic impedance of high-frequency (≥100 MHz) ultrasound transducers to an aqueous loading medium remains a challenge for fabricating high-frequency transducers. Fong, Wayne Chen, Zeyu Zhu, BenPeng Xiong, Rui Shi, Jing Hsiai, Tzung K. ![]() This design of the high frequency magnetostrictive transducer retains the beneficial aspects of the magnetostrictive design, while reducing its primary drawback, lower frequency operation.ĭesign of matching layers for high-frequency ultrasonic transducersįei, Chunlong Ma, Jianguo Chiu, Chi Tat Williams, Jay A. High frequency magnetostrictive transducers for waveguide applicationsĭOE Office of Scientific and Technical Information (OSTI.GOV)ĭaw, Joshua Earl Taylor, Steven Cheney Rempe, Joy LynnĪ high frequency magnetostrictive transducer includes a magnetostrictive rod or wire inserted co-axially into a driving coil, wherein the driving coil includes a coil arrangement with a plurality of small coil segments along the magnetostrictive rod or wire wherein frequency operation of the high frequency magnetostrictive transducer is controlled by a length of the small coil segments and a material type of the magnetostrictive rod or wire. ![]()
