摘要：
Approximate image type expressions for series impedance and shunt admittance are derived for self and mutual coupling of wires above, on, and under a lossy ground. The expressions are used for approximate evaluation of the propagation constant and the characteristic impedance of a single wire of general location relative to the surface of ground. Numerical comparisons with exact and quasi-TEM results are presented.
