Efficient utilization of electrical insulating materials in electrical apparatus, devices, and cables requires knowledge of the dielectric loss behavior of materials under specific voltage, frequency, and temperature conditions. The appearance of significant dielectric losses may not only represent an unnecessary energy loss but could possibly lead to ...

Optical losses in dielectric films
Thin Solid Films, 1976High quality optical resonators for laser and Fabry-Perot interferometer and narrow band interference filters consist of a variable number of dielectric films which should not cause optical attenuation in the desired wavelength region. Related to the growth of integrated optics technology, this trend towards exceptionally high quality optical materials

Relaxation in low-loss dielectrics
Journal of Molecular Liquids, 2000Abstract The real and imaginary components of the complex susceptibility of the majority of non-polar dielectric materials follow a fractional power law dependence on frequency known as the “universal law”. One limiting form of this law shows a very low loss and also a nearly frequency-independent, or “flat” amplitudes.

1967
In alternating electric fields, a dielectric material is frequently characterized by its dielectric loss, which depends on the fraction of electrical energy lost to heat, rather than by its electrical conductivity. The energy loss occurs as the result of two processes: conduction and slow polarization currents.

Low-Loss Multilayer Dielectric Mirrors
Applied Optics, 1965The preparation of low-loss multilayer dielectric coatings for laser mirrors is described. Layer thickness is controlled by a unique monitoring system utilizing a 6328-A gas laser as a light source. Experiments designed to evaluate and reduce losses in the mirror coatings are discussed.
