The broad band transducer has generalized in the ultrasonic non-destructive testing these days. A received waveform of 1.5 cycles has widely been used, and a received waveform of one cycle is near completion for practical use. The market demands a higher resolution and a wider band transmitted and received pulse than they are. Under these circumstances, this development was carried out for the purpose of generation and receiving of a 0.5 cycle or shorter pulse.
