摘要
从理论上介绍一种利用叉指换能器制作高频声体波换能器的方法,具有结构和工艺简单,声波模式纯度较高,换能损耗较小和容易消除各种反射波影响的特点。
n this paper,a new kind of high frequency bulk acoustic wave transducer consis-ting of interdigital electrodes on the surface of piezoelectric material is introduced theoretically.The method possesses the advantages of simple structure,pure mode,low conversion loss and easyeliminating the effects of reflected waves.
