[1930–35] mi′cro•wav`a•ble, adj. ![]() microwaveA microwave oven is activated when an electric current causes a magnetron to emit a beam of microwaves. The beam is distributed throughout the unit by a rotating reflector. The microwaves agitate water molecules in the food, generating enough heat to cook it.mi·cro·wave (mī′krō-wāv′)1.

Translationsmicrowave (ˈmaikrəweiv) noun (also microwave oven) an oven that heats or cooks food very quickly using electromagnetic waves. 微波 微波 verb to cook or heat something in a microwave. 用微波爐烹調或加熱 用微波炉烹调或加热microwave
microwave, electromagnetic wave having a frequency range from 1,000 megahertz (MHz) to 300,000 MHz, corresponding to a wavelength range from 300 mm (about 12 in.) to 1 mm (about 0.04 in.). Like light waves, microwaves travel essentially in straight lines. They are used in radar, in communications links spanning moderate distances, and in other applications, such as microwave ovensmicrowave oven,
device that uses microwaves to rapidly cook food. The microwaves cause water molecules in the food to vibrate, producing heat, which is distributed through the food by induction. A special electron tube called a magnetron produces the microwaves.

(as modifier): microwave generator microwaveMeaning "small wave," a microwave is a radio signal in the frequency range from 300 MHz to 300 GHz or from 1 to 300 GHz, depending on the rating system. Except for AM and FM radio, shortwave radio and over-the-air TV, almost all other communications systems transmit microwaves, including satellites, cellular systems, wireless LANs and line-of-sight between buildings and across vast distances. See spectrum and millimeter wave.

| Line-of-sight microwaves were first used to transmit across long distances where the terrain was too difficult to lay cable. This tower was installed in 1969 in Boulder Junction, Colorado. (Image courtesy of AT&T.) |
microwave
microwave [mi´kro-wāv] a wave typical of electromagnetic radiation between far infrared and radiowaves.microwave A 1–100 gigaHerz (109) wave on the electromagnetic spectrum with a wavelength of 1–1000 mm.
Public health
Exposure to microwaves is linked to domestic microwave ovens; leakage of infrared waves ranges from 1 milliWatt/cm2 at the time of sale of a microwave oven to 5 mW/cm2, measured at a distance of 2 inches. Older pacemakers tended to misfire when the wearer was exposed to early microwave ovens, which were also linked to an increase in cataracts.
Hazards
Mechanical—eggs and popcorn are particularly hazardous, as they can explode, and the microwaving of metallic objects can result in a fire hazard.
There is little data to suggest that microwave exposure is associated with increased morbidity.microwave Therapeutics Deep heat therapy The administration of electromagnetic waves that pass between electrodes placed on the Pt's skin, creating heat that ↑ blood flow and relieves muscle and joint painSee MW
