  2. Microwave oven - Wikipedia

    en.wikipedia.org/wiki/Microwave_oven

    A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to vibrate [2] and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently ...

  4. Microwave - Wikipedia

    en.wikipedia.org/wiki/Microwave

    Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves. Its wavelength ranges from about one meter to one millimeter, corresponding to frequencies between 300 MHz and 300 GHz, broadly construed. [1][2]: 3 [3][4][5][6] A more common definition in radio-frequency engineering ...

  5. Microwave burn - Wikipedia

    en.wikipedia.org/wiki/Microwave_burn

    The U.S. Food and Drug Administration (FDA) standard for microwave oven leakage puts limit to 5 mW/cm 2 at 2 inches from the oven's surface. [25] For 5.8 GHz, exposure to 30 mW/cm 2 causes increase of facial skin temperature by 0.48 °C, corneal surface heats by 0.7 °C, and the temperature of retina is estimated to increase by 0.08–0.03 °C.

  6. Super high frequency - Wikipedia

    en.wikipedia.org/wiki/Super_high_frequency

    e. Super high frequency (SHF) is the ITU designation for radio frequencies (RF) in the range between 3 and 30 gigahertz (GHz). This band of frequencies is also known as the centimetre band or centimetre wave as the wavelengths range from one to ten centimetres. These frequencies fall within the microwave band, so radio waves with these ...

  7. Dielectric heating - Wikipedia

    en.wikipedia.org/wiki/Dielectric_heating

    Dielectric heating, also known as electronic heating, radio frequency heating, and high-frequency heating, is the process in which a radio frequency (RF) alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material. At higher frequencies, this heating is caused by molecular dipole rotation within ...

  9. Trivection oven - Wikipedia

    en.wikipedia.org/wiki/Trivection_oven

    The Trivection oven is a convection microwave created by General Electric, which combines radiant heat, convection, and microwaves for customized cooking. According to GE, it cooks food five times faster than a traditional oven. [1] Alton Brown, host of Good Eats, was involved in developing the oven.
