| Abstract: | In this paper, a kind of three-phase piezoelectric composite material'sstructure and its manufacturing method are introduced. This material is of 2-2structure charateristics. While it is compared with a kind of two-phase piezoelectriccomposite of similar structure, measurement and discussion on cross-coupling,frequency charateristics, acoustic impedance, and dielectric property are taken. Theresult that this three-phase composite was applied to linear array successfully isshowed at same time. |
