Wave Travel: The wavelength of a wave, {eq}\lambda {/eq} (m), is the distance the wave travels in one cycle. The period of a wave, {eq}T {/eq} (s), is the time for one cycle of the wave to pass a given point. If the speed at which ...

A wavelength-division-multiplexed (WDM) radio-over-fiber (RoF) de-multiplexer, which is specially designed for frequency-modulated continuous-wave (FM-CW) signal delivery systems, is newly developed. The characteristics of the developed de-multiplexer are described and then the de-multiplexing perform...
Fréquence Gaie came under pressure to share its FM wavelength with other newly licensed stations. Opposition to this may have provided the impetus for the station’s decision to appoint an outreach officer, Jean-Luc Romero, to raise its profile and attempt to extend its reach to other ...

The Etón Elite Field receives most every radio wavelength—AM (MW), FM, and Shortwave (SW)—at home or abroad. It's easy to set the station spacing and frequency so your stations come in loud and clear wherever you are. And with Bluetooth®, you can stream your own music or ...
Weather radars resemble search radars, but use radio waves with circular polarization and a wavelength to reflect from water droplets. Some weather radar use the doppler to measure wind speeds. Emergency services emergency position-indicating rescue beacons (EPIRBs), emergency locating transmitters or...
Microwave spectrum includes 3 GHz–30 GHz and it has become a potential alternative solution to optical fiber communication (OFC) by supporting higher data rate communication. Because of the difference in wavelength or frequency, the attenuation characteristics of microwaves vary from lasers. In Ref....
