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
Dielectric Resonator Antenna — If the dielectric resonator is placed in an open environment, power is lost in the radiated fields. This fact makes dielectric resonators useful as antenna elements. Dielectric resonator antennas (DRA) offer following attractive features: The… … Wikipedia
Dielectric heating — A microwave oven, which uses dielectric heating to cook food Dielectric heating, also known as electronic heating, RF heating, high frequency heating and diathermy, is the process in which a high frequency alternating electric field, or radio… … 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
