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.
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 .
Microwave ovens put out 1,000 watts commonly, and still the unfocused beam degrades exponentially in air, to the point that a couple meters is safe distance from an unfocused, operating magnetron. in contrast, microwave transmission antennas usually use 1 or 2 watts of power. they are focused/colliminated, and are yet still not powerful enough to cause the mentioned deep tissue burns.
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 ...
Non-thermal microwave effects or specific microwave effects have been posited in order to explain unusual observations in microwave chemistry. The main effect of the absorption of microwaves by dielectric materials is a brief displacement in the permanent dipoles which causes rotational entropy.
The absorption (equivalent to dielectric loss) is used in microwave ovens to heat food that contains water molecules. A frequency of 2.45 GHz , wavelength 122 mm, is commonly used. Radiocommunication at GHz frequencies is very difficult in fresh waters and even more so in salt waters.
LC circuit equivalent for microwave resonant cavity. Microwave resonant cavities can be represented and thought of as simple LC circuits, see Montgomery et al pages 207-239. [15] For a microwave cavity, the stored electric energy is equal to the stored magnetic energy at resonance as is the case for a resonant LC circuit.
The Trivection oven is a convection microwave created by General Electric, which combines radiant heat, convection, and microwaves for customized cooking. According to GE, it cooks food five times faster than a traditional oven. [1] Alton Brown, host of Good Eats, was involved in developing the oven. [2]
