| Abstract: | According to the equivalent circuit net analysis method of piezoelectric transducer, we have calcuated the three piezoelectric transducer functional relationship between normalized input impedance ｜Z_i｜ and normalized frequency f/f_0 ror the x-cut LN/mercurous chloride acousto-optic devices using expoxy resin polymer as buffer coat and drawn the ｜Z_j｜-f/f_0 cube graph. From these we can come to a conclusion that the input impedance is the complex number function of frequency f, the input impedance presents the inductance or capacitance impedance in different frequency ranges, the input impedance will be changued if the the elestrde layers is changed. |
