| Abstract: | Based on the method of equivalent circuit net analysis,we have worked out the functional relationship between normalized input impedance |Zi| and normalized frequency f/f0 for piezoelectric transducer 36°Y-cut LN/PM acousto-optic devices;obtained the 3D |Zj|-f/f0 graph;concluded that the input impedance is a complex plural function of frequency,and presents capacitance impedance throughtout the frequency range. |
