Abstract
The electric field E in a poled dielectric is calculated numerically taking into account its electrical conductivity as a function of the driving frequency and the dielectric relaxation time. The conditions are determined for E to be independent of the driving frequency, stabilizing the characteristics of the transducers. Practical recommendations are given for choosing the electrophysical parameters of piezoelectric materials for infrared radiation modulators.
