Dielectric Loss Mechanism in Rutile (TiO2)
Journal of Applied Physics, 1972A new mechanism to account for the anomalously large dielectric loss and apparent dielectric constant frequently observed in TiO2 is presented, which appears to agree well with experiment. The mechanism involves field-induced donor migration where the field arises from a difference in work function between the rutile and a metal electrode.

Low-loss dielectrics are important technologically as insulators but there is little understanding of the physical causes of this property and even their spectral response is not well documented—this study has revealed a number of different types of behaviour which do not appear to have been recognised previously. Most low-loss materials show a “flat”,

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 ...

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.

Dielectric Polarization and Loss
Annual Review of Physical Chemistry, 1960The subject of dielectric behavior has not previously been dealt with as such in these reviews, although dielectric properties relevant to other sub jects have often been mentioned. There have, however, been a number of comparatively recent books and review articles on various aspects of di electrics.

Losses at corner bends in dielectric waveguides
Applied Optics, 1977An approximate technique based on a sum rule is used to treat mode conversion at corner bends in dielectric waveguides. Matrix elements which describe the mode coupling are expressed as spatial integrals over electromagnetic field distributions for the guided modes.
