  2. Microwave oven - Wikipedia

    en.wikipedia.org/wiki/Microwave_oven

    A microwave oven, c. 2005 Simulation of the electric field inside a microwave oven for the first 8 ns of operation. A microwave oven heats food by passing microwave radiation through it. Microwaves are a form of non-ionizing electromagnetic radiation with a frequency in the so-called microwave region (300 MHz to 300 GHz).

  3. 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.

  4. ISM radio band - Wikipedia

    en.wikipedia.org/wiki/ISM_radio_band

    The bands are still widely used for these purposes. For many people, the most commonly encountered ISM device is the home microwave oven operating at 2.45 GHz which uses microwaves to cook food. Industrial heating is another big application area; such as induction heating, microwave heat treating, plastic softening, and plastic welding processes.

  5. Microwave radiometer - Wikipedia

    en.wikipedia.org/wiki/Microwave_radiometer

    A microwave radiometer (MWR) is a radiometer that measures energy emitted at one millimeter-to-metre wavelengths (frequencies of 0.3–300 GHz) known as microwaves. Microwave radiometers are very sensitive receivers designed to measure thermally-emitted electromagnetic radiation. They are usually equipped with multiple receiving channels to ...
