dielectric heating उदाहरण वाक्य

Dielectric heating at low frequencies, as a near-field effect, requires a distance from electromagnetic radiator to absorber of less than } } H " of a wavelength.
Is it possible to heat rock like granite by using dielectric heating or induction heating . . ? talk ) 05 : 46, 1 November 2012 ( UTC)
Dielectric loss is caused when the insulating material inside the transmission line absorbs energy from the alternating electric field and converts it to heat ( see dielectric heating ).
The " high-frequency dielectric heating apparatus " invented by Spencer was patented in 1953, and the first ovens were named " radar ranges " in reference to their discovery.
Diathermy is used by some as a synonym for electrosurgery but in other contexts diathermy means dielectric heating, produced by rotation of molecular dipoles in a high frequency electromagnetic field.

In agriculture, RF dielectric heating has been widely tested and is increasingly used as a way to kill pests in certain food crops after harvest, such as walnuts still in the shell.
Dielectric heating of liquid water is also temperature-dependent : At 0 �C, dielectric loss is greatest at a field frequency of about 10 GHz, and for higher water temperatures at higher field frequencies.
Shigeru Nakajima, a younger brother of Yoji Ito and a scientist at the Japan Radio Company ( JRC ), was also investigating magnetrons, primarily for the medical dielectric heating ( diathermy ) market.
A microwave oven passes ( non-ionizing ) microwave radiation at a frequency near [ [ ISM band | ] ] through food, causing dielectric heating primarily by absorption of the energy in water.
Nevertheless, the primary heating effect of all types of electromagnetic fields at both radio and microwave frequencies occurs via the dielectric heating effect, as polarized molecules are affected by a rapidly alternating electric field.
