摘要
本文提出薄膜叉指换能器叉指边界上的电位分布和电荷分布的解析函数模型。用该模型计算声表面波薄膜叉指换能器的静态电容在金属化比α取[1/16,13/16]时,其误差只有千分之几。
This paper proposed a model of analytic function for determining the potential and charge distributions on interdigital boundaries of film interdigital transducers. The static capacitances of film SAW interdigital transducers have been calculated using this kind .of model. When metallization ratio a is [1/16, 3/16], the error in calculation is
