Polarization of Radio Waves

Transactions of the American Institute of Electrical Engineers, 1926
UNTIL rather recently, the practise of radio communication was confined to the use of long, earth-bound waves. These waves are preferred on account of the regularity of day and night operation and the absence of fading. The characteristics of the earth-bound wave were extensively explored and there was a tendency to generalize these results assuming ...

Radio Wave Tomography: Imaging Ore Bodies Using Radio Waves

3rd SAGA Biennial Conference and Exhibition, 1993
Radio tomography (RT) extrapolates geological information between boreholes, by producing attenuation images of the intervening rockmass. In this paper the underlying principles of this novel geophysical technique are described, and case studies from a variety of geological and rnining environments are presented.

Radio Wave Propagation

AIP Conference Proceedings, 2007
Electromagnetic radio waves traveling within earth’s atmosphere are called terrestrial waves, and communications between two or more points on earth is called terrestrial radio communications. Terrestrial waves are influenced by the atmosphere and earth itself.
