A novel structure of high voltage transducer's head is designed in this paper. Three pieces of quartz crystal is
sandwiched between four metal electrodes. The converse piezoelectric effect of quartz crystal is used to sense the voltage
applying on the transducer. In this paper, more attention is paid to selection of the crystal material, the shape of the
electrode, the electrode material, the dimension of the electrode, and the distance of the electrode. After simulated with
finite element method, the distribution of electric field at different condition is obtained. At last, an experiment is set up
to validate the feasibility of applying intermodal interference in elliptical-core polarization maintenance fiber (E-core
PMF) on high voltage transducer.
