  • Dielectric — A dielectric 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 in a conductor, but only slightly shift from their …   Wikipedia

  • Dissipation factor — In physics, the dissipation factor (DF) is a measure of loss rate of energy of a mode of oscillation (mechanical, electrical, or electromechanical) in a dissipative system. It is the reciprocal of Quality factor, which represents the quality of… …   Wikipedia

  • Dielectric spectroscopy — A dielectric permittivity spectrum over a wide range of frequencies. The real and imaginary parts of permittivity are shown, and various processes are depicted: ionic and dipolar relaxation, and atomic and electronic resonances at higher energies …   Wikipedia

  • Dielectric resonator — A dielectric resonator (also dielectric resonator oscillator, DRO) is an electronic component that exhibits resonance for a narrow range of frequencies, generally in the microwave band. The resonance is similar to that of a circular hollow… …   Wikipedia
