Frequency Character of Piezoelectric Transducer Hg2Br2 Ao Devices |

| Abstract: | This paper presents method using epoxy resin ploymer as buffer coat between the transducer and Hg2Br2 acousto optic crystal to design the three and five layer transducer for Hg2Br2 Ao devices.According to the equivalent circuit net analysis method,we have calculated the functional relationship between three and five layer transducer loss TL and normalized frequency f/fo the functional relationship between normalized input impedance |Zi|and normalized frequency f/fo for the x-cut LN/Hg2Br2 AO devices. |
