Simple expressions for horizontal electric dipole quasi-static range subsurface-to-subsurface and subsurface-to-air propagation

摘要

Simple engineering expressions for the quasi-static fields produced by a subsurface horizontal-electric-dipole (HED) antenna have been derived by employing finitely conducting earth-image theory techniques. Both subsurface-to-subsurface and subsurface-to-air propagation cases are considered. It is shown that the resulting subsurface-to-air propagation field-strength expressions are the result of simple modifications to the previously derived quasi-static range air-to-air propagation equations of one of the authors.
