  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 (heat) in a process known as dielectric heating .

  3. Isolator (microwave) - Wikipedia

    en.wikipedia.org/wiki/Isolator_(microwave)

    At microwave frequencies, this material is usually a ferrite which is biased by a static magnetic field [1] but can be a self-biased material. [2] The ferrite is positioned within the isolator such that the microwave signal presents it with a rotating magnetic field, with the rotation axis aligned with the direction of the static bias field.

  4. 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 ...

    Putting a non-microwave-safe material in a microwave oven can lead to chemicals leaching into your food (not good) or the melting of the container, which can lead to burns — or, at the very ...

  6. mp3DirectCut - Wikipedia

    en.wikipedia.org/wiki/Mp3DirectCut

    By modifying the global gain field of each frame of MPEG audio, the volume of that frame can be modified without altering the audio data itself. This allows for rapid, lossless MP3 audio editing that does not degrade the data from re-encoding. mp3DirectCut provides audio normalization and pause (silence) detection, and can split long recordings ...

  7. 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.

  8. Maser - Wikipedia

    en.wikipedia.org/wiki/Maser

    The term is an acronym for microwave amplification by stimulated emission of radiation. Nikolay Basov , Alexander Prokhorov and Joseph Weber introduced the concept of the maser in 1952, and Charles H. Townes , James P. Gordon , and Herbert J. Zeiger built the first maser at Columbia University in 1953.

  9. 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.
