Dielectrics and electrooptics

Abstract

The present chapter describes the physical properties of dielectrics dielectricphysical properties and includes the following data: 1.Low-frequency propertiesdielectriclow-frequency properties, i. e., density and Mohs hardness, thermal conductivity, static dielectric constant, dissipation factor (loss tangent), elastic stiffness and elastic compliance, and piezoelectric strain2.High-frequency (optical) propertiesdielectrichigh-frequency (optical) properties, i. e., elastooptic and electrooptic coefficients, optical transparency range, two-photon absorption coefficient, refractive indices and their temperature variation, dispersion relations (Sellmeier equations), and second and/or third-order nonlinear dielectric susceptibilities.
