2. Microwave oven - Wikipedia

   en.wikipedia.org/wiki/Microwave_oven

   Globally. 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 ...

3. Microwave - Wikipedia

   en.wikipedia.org/wiki/Microwave

   Microwave. A telecommunications tower with a variety of dish antennas for microwave relay links on Frazier Peak, Ventura County, California. The apertures of the dishes are covered by plastic sheets (radomes) to keep out moisture. Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves (as originally ...

4. Cavity magnetron - Wikipedia

   en.wikipedia.org/wiki/Cavity_magnetron

   The modern magnetron is a fairly efficient device. In a microwave oven, for instance, a 1.1-kilowatt input will generally create about 700 watts of microwave power, an efficiency of around 65%. (The high-voltage and the properties of the cathode determine the power of a magnetron.)

5. These Microwaves Cost $150 or Less, But They Don’t Look It

   This Black+Decker microwave oven offers decent size and power for under $100, making it one of the best options you can get at this price point. Its interior is 0.7 cubic feet, and its glass ...

6. 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.

7. Microwave cavity - Wikipedia

   en.wikipedia.org/wiki/Microwave_cavity

   Microwave cavity. Two microwave cavities (left) from 1955, each attached by waveguide to a reflex klystron (right) a vacuum tube used to generate microwaves. The cavities serve as resonators (tank circuits) to determine the frequency of the oscillators. A microwave cavity or radio frequency cavity (RF cavity) is a special type of resonator ...
