【Abstract】 This paper discusses an optical fiber sensor coated with piezoelectric ZnO. The geometry of optical fiber using ZnO coating has firstly been presented and the basic theory of piezoelectric resonator of this geometry been analyzed. Also, the equivalent network model for the optical fiber sensor coated with piezoelectric ZnO has been given. And then, the reflection coefficient S11 has been obtained by this model. Finally, simulation of S11 has been made according to the practical parameters.更多还原
