절연판이 복합압전진동자의 공진주파수에 미치는 영향 = Effects of the Insulator on the Resonant Frequency of a Composite Piezoelectric Vibrator

다국어 초록 (Multilingual Abstract)

This paper introduces a technique of changing the resonant frequency and of depressing the spurious modes in the composite piezoelectric vibrator laminated in the order of piezoelectric vibrator/thin insulator/piezoelectric vibrator, whose vibrators have the same sizes and the same properties, respectively.
The composite vibrator has shown the characteristics that the fundamental resonant frequency has decreased and spurious nodes lave depressed with increase of the capacitance of the inserted insulator. And the frequency characteristics of the composite vibrator without insulator have been nearly the some as those of each vibrator.
