Greatly used in air-borne communications, for example with mobile phones. The shorter the wavelength the greater the bandwidth. However this is still only theory since security precautions would have to be considered to prevent these satellites from being hijacked and turned against civilian areas for the purpose of frying people. Note the size of these wavelengths - the longer microwaves' wavelengths are literally measured in centimeters. Contrast this with gamma rays, whose wavelengths are sub-atomic in size.
Many stars are microwave emitters.
Receivers containing inductance and capacitance which are set into resonance by the wave. Up to my Academic Projects Page . Up to my Home Page . Text last updated in September 1997. Document last updated in October 1998.
