Simple, closed-form expressions have been derived for the propagation constants and currents for a two-conductor transmission line over earth with a single shield wire centered above it and periodically grounded through an impedance. Each conductor is driven by a voltage source at $\mathrm{z}=$ 0. The expressions are valid as long as all transverse dimensions are small compared to a free-space wavelength, are in agreement with the known low-frequency expressions, and can be used to establish… CONTINUE READING
