Sentences with phrase «than microwave frequencies»

The logic clock is based on a single aluminum ion (electrically charged atom) trapped by electric fields and vibrating at ultraviolet light frequencies, which are 100,000 times higher than microwave frequencies used in NIST - F1 and other similar time standards around the world.

Not exact matches

Rather than dangerous X-rays, however, the chip beams out waves in the harmless terahertz frequency, a little - used portion of the electromagnetic spectrum between microwaves and far - infrared.

At radio frequencies greater than 10 gigahertz the radio emission matched that of the microwave background, but at lower frequencies it was several times stronger.

The second is currently defined by caesium atomic clocks, but optical clocks promise higher precision because their atoms oscillate at the frequencies of light rather than in the microwave band, so they can slice time into smaller intervals.

Such clocks should be easy to fashion; optical light «ticks» a thousand times faster than lower frequency microwaves.

The higher frequencies mean that optical clocks «tick» faster than microwave atomic clocks and could thus provide time - stamps that are 100 to 1,000 times more accurate, greatly improving the precision of GPS.

The vibrations also have wavelengths less than a thousandth as long as microwaves of the same frequency, so the resonators can be far more compact, he says.

The accuracy and the stability of optical clocks are mainly based on the fact that the frequency of the optical radiation used is higher (by several orders of magnitude) than that of the microwave radiation which is used in cesium atomic clocks, which makes optical clocks much more precise than cesium clocks.

But then I had to go through this research because your cellphone might be operating on a very different frequency of radiation than your microwave.

Like Ku - band service, Ka - band is also named after a range of microwave frequencies and uses satellite rather than air - to - ground technology.
