Electromagnetic ultrasound transducer

摘要

A handheld, compact, self-contained transducer unit for electromagnetic generation and detection of ultrasound on or in metals and other media is realized by mounting short, flat cable sections directly on a small, powerful permanent magnet. The cable sections are interconnected in an electromagnetic transducer circuit configuration and the plane of the flat cable transducer circuit structure is perpendicular to the magnet magnetization axis. Fabrication of the device can be accomplished by selectively connecting the conductor ends of a flat strip electrical conductor segment and affixing the conductor segment to an appropriate surface of a samarium-cobalt permanent magnet.
