ABSTRACT:
1. A method of radio transmission comprising radiating electromagnetic waves in the earth's crust through a "deep wave guide" formed of basement rock bounded on its upper side by a surface layer of sufficient conductivity to form the upper boundary of the wave guide and bounded on its lower side by a region having a temperature of several hundred degrees Centigrade, which temperature causes the lower region to have a conductivity which is high relative to that of the basement rock.
