    Sometimes, abnormal beeping from your microwave can signal that there’s something wrong, whether that be a need for new batteries or a new appliance overall. Either way, it’s best to contact a ...

  3. Security alarm - Wikipedia

    en.wikipedia.org/wiki/Security_alarm

    Compact surveillance radar emits microwaves from a transmitter and detects any reflected microwaves. They are similar to microwave detectors but can detect the precise location and a GPS coordinate of intruders in areas extending over hundreds of acres. It has the capability of measuring the range, angle, velocity, direction, and size of the ...

  4. Microwave transmission - Wikipedia

    en.wikipedia.org/wiki/Microwave_transmission

    Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter , but such systems are expensive and generally used only in ...

  5. Microwave engineering - Wikipedia

    en.wikipedia.org/wiki/Microwave_Engineering

    The microwave engineering discipline has become relevant as the microwave domain moves into the commercial sector, and no longer only applicable to 20th and 21st century military technologies. Inexpensive components and digital communications in the microwave domain have opened up areas pertinent to this discipline.

  8. 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.

  9. Cavity magnetron - Wikipedia

    en.wikipedia.org/wiki/Cavity_magnetron

    In microwave-excited lighting systems, such as a sulfur lamp, a magnetron provides the microwave field that is passed through a waveguide to the lighting cavity containing the light-emitting substance (e.g., sulfur, metal halides, etc.). Although efficient, these lamps are much more complex than other methods of lighting and therefore not ...
