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, 1993Radio 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.

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.

IRE Transactions on Antennas and Propagation, 1957
The formulas required for simple accurate numerical evaluation of the radiation patterns from slots on large circular cylinders are derived. From the usual harmonic series, integral representations are obtained. These lead to either the residue series via the Watson transformations or to the geometrical-optics representations via a saddle-point ...
