초록
The method of suppression based on the principle of energy trapping effect is very effective at high frequency. In this paper, We intended to get resonant frequency and bandpass filer characteristics in appling to vibration mode of PZT-4 and PZT-8 using trapped energy phenomenon. First, we theoretically analyzed a piezoelectric ceramic filter characteristics changing the thickness of ceramic plate, electrode spacing and distance between the two pairs of electrodes. We also experimentally investigated characteristics of ceramic filter made.
