单词 | dielectric heating |
释义 | dielectric heating The heating of a dielectric material, such as a plastic, by applying a radio-frequency electric field to it. The most common method is to treat the material as the dielectric between the plates of a capacitor. The heat produced is proportional to V2fAφ/t, where V is the applied potential difference,f its frequency, A is the area of the dielectric, t its thickness, and φ is the loss factor of the material (related to its permittivity) |
