  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 rotate and produce thermal energy in a process known as dielectric heating .

  3. Microwave transmission - Wikipedia

    en.wikipedia.org/wiki/Microwave_transmission

    A microwave link is a communications system that uses a beam of radio waves in the microwave frequency range to transmit video, audio, or data between two locations, which can be from just a few feet or meters to several miles or kilometers apart.

  4. Dielectric heating - Wikipedia

    en.wikipedia.org/wiki/Dielectric_heating

    A microwave oven uses dielectric heating to cook food.. 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.

  5. Microwave - Wikipedia

    en.wikipedia.org/wiki/Microwave

    A microwave oven passes microwave radiation at a frequency near 2.45 GHz (12 cm) through food, causing dielectric heating primarily by absorption of the energy in water. Microwave ovens became common kitchen appliances in Western countries in the late 1970s, following the development of less expensive cavity magnetrons. Water in the liquid ...

    Specialties include microwave and RF integrated circuit design, antenna engineering, computational electromagnetics, radiowave propagation, radar and remote sensing systems, image processing, and THz imaging. [5] [6] Tufts University offers a Microwave and Wireless Engineering certificate program as part of its graduate studies programs. It can ...

  7. Microwave heat distribution - Wikipedia

    en.wikipedia.org/wiki/Microwave_Heat_Distribution

    The microwave heat distribution is the distribution (allocation) of the heat release inside the microwave absorptive material irradiated with high intensive microwaves.The pattern of microwave heat distribution depends on many physical parameters, which may include the electromagnetic field, the specific absorption rate and structure of the processed material, the geometrical dimensions of the ...
