a short electromagnetic wave (longer than infrared but shorter than radio waves); used for radar and microwave ovens and for transmitting telephone, facsimile, video and data
Sending high frequency radio waves from a tower at one point through the air to a receiving dish at another site
1) Any electromagnetic radiation with a wavelength between 1 millimeter and 1 meter 2) A point-to-point data transmission system employing electromagnetic radiation using a carrier frequency in the microwave region
(communications usage) High-frequency radio waves used for point-to-point and omnidirectional communication of audio, data and video signals Microwave frequencies require direct line-of-sight to operate; obstructions such as trees or building distort the signal
A form of electromagnetic radiation that is beyond the range of the visible light spectrum Microwaves have very high frequencies and wavelengths of 1 mm to 50 cm
The frequency range from approximately 1 to 300 GHz, covering the frequency range suitable for satellite communications
That portion of the electromagnetic spectrum extending in frequency from 500 million cycles per second (500 MHz) up to the frequencies of visible light
High-frequency radio waves used for point-to-point and omni-directional communication of audio, data and video signals Microwave frequencies require direct line of sight between sending and receiving station to operate Microwave systems were the preferred method of communications transmission before the introduction of fiber optic
The range in the electromagnetic spectrum from 300 MHz to 30 GHz (with corresponding wavelengths from 100 cm to 1 cm)
A signal in the generic frequency range from above 1 GHz to an upper end of perhaps 30 or 40 GHz
A term loosely applied to those radio frequency wavelengths which are sufficiently short to exhibit some of the properties of light Commonly used for frequencies from about 1 GHz to 30 GHz
A microwave or a microwave oven is an oven which cooks food very quickly by electromagnetic radiation rather than by heat
Electromagnetic waves in radio frequencies above 890 MHz and below 20 GHz They only travel in straight lines, and are used for communication between satellites
Circuitry operating at frequencies where the wavelength is 1mm to 30cm (300GHz to 1GHz) - between radio and infra-red wavelengths Such frequencies on PCB require extreme attention to exact track form
To microwave food or drink means to cook or heat it in a microwave oven. Steam or microwave the vegetables until tender. to cook something in a microwave oven. Portion of the electromagnetic spectrum that is situated between radio waves and infrared radiation. Microwaves have wavelengths ranging from 30 cm to 1 mm, corresponding to frequencies from about 1 gigahertz (10^9 Hz) to 1 terahertz (10^12 Hz). They are the principal carriers of television, telephone, and data transmissions between stations on Earth and between the Earth and satellites. Radar beams are short pulses of microwaves used to locate ships and planes, track weather systems, and determine the speeds of moving objects. Microwaves are absorbed by water and fat in foodstuffs and produce heat from the inside (see microwave oven). Materials such as glass and ceramics do not absorb microwaves, and metals reflect them.
