Description |
Ultrasonic piezoelectric transducers that are employed in various applications are desired to produce a broadband frequency spectrum. However, interference from the sympathetic pulses generated by the transducer limits the duration of the waveform to a very short time. This paper discusses grading of the transducer as a means of alleviating the sympathetic pulses. A simple one-dimensional model based on the spectral approach has been presented. The piezoelectric constant e(33) is graded in various manners and their performances are evaluated. The signal qualities are evaluated through their Euclidean distances from the applied voltage pulse. Linearly graded transducers show the best results.
