MODES IN LOSSY STRATIFIED MEDIA WITH APPLICATION TO UNDERGROUND PROPAGATION OF RADIO WAVES,

Abstract

The problem considered is that of determining the complex propagation constant of a plane wave on a flat layer of lossy dielectric with a loss-tangent, less than one, and of uniform thickness, surrounded on both sides by identical layers having a loss-tangent greater than the skin depth. A formula given, relating this propagation constant to the path loss between two antennas provided their excitation efficiencies are known. Frequencies between 1 kc/s and 10 Mc/s are covered, as well as values on thickness of the middle layers ranging from 10 meters to 200 meters. (Author)
