Abstract

The theory was analyzed and the computer program was developed for simulation about ceramic filter in the state of the one-strip electrode using the energy trapping effect. They were fabricated using the PZT-4 specimen. Each of the average differances of the resonant point and bandwidth between by the theoretical calculations and by experiment results was 5.6[%] and 3.72[%], and it is considered that this differance is originated from the high temperature and stress during the process that the ceramic filter was fabricated It is considered that the one-strip ceramic filter having a wanted characteristics and the lowest differance is fabricated easily by means of the simulation developed in this paper and the fabrication methods.
