Abstract:
A contact shear horizontal (SH) mode guided-wave magnetostrictive transducer including: a transduction band which is disposed on a surface of an object to be tested and in which electromagnetic acoustic transduction occurs; and radio frequency (RF) coils disposed on the transduction band, wherein the transduction band includes a plate-shaped solenoid including a magnetostrictive strip in which the electromagnetic acoustic transduction for transmitting or receiving SH mode guided waves occurs, and solenoid coil wound in a spiral form along a circumference of the magnetostrictive strip so as to form a bias magnetic field in a lengthwise direction of the magnetostrictive strip, and the RF coils are used to form a dynamic magnetic field in a widthwise direction of the magnetostrictive strip or to detect a change of magnetic flux in the magnetostrictive strip.
