The Relationship Between Loss, Conductivity, and Dielectric Constant
... Most atoms have a cloud of electrons surrounding the nucleus. Since the mass of an electron is much less than the mass of the nucleus, the application of an electric field causes the electrons to react and move much more quickly than the nucleus can react. The result is that the electron cloud shift ...

... Tillmanns9 synthesized a single crystal of BaTi2 O5 by rapid solidification from a melt with a composition of BaCO3 :TiO2 540:60 in molar ratio, and the crystal structure was refined using the data collected with a four-cycle x-ray diffractometer. This resulted in a much better fit as evidenced by t ...

Dielectric
A dielectric material (dielectric for short) is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift in the opposite direction. This creates an internal electric field that reduces the overall field within the dielectric itself. If a dielectric is composed of weakly bonded molecules, those molecules not only become polarized, but also reorient so that their symmetry axes align to the field.The study of dielectric properties concerns storage and dissipation of electric and magnetic energy in materials. Dielectrics are important for explaining various phenomena in electronics, optics, and solid-state physics.
