Abstract

The dependence of TE-mode wave-tilt on frequency and altitude of measurement, and the resistivity and dielectric constants of the ground have been investigated. Computational results showing the influence of these parameters on the amplitude and phase of the wave-tilt over a homogeneous half-space earth model have been presented. In contrast to TM-mode waves, the wave-tilt effects for TE-mode are stronger in the lower frequency region. In the lower frequency range, the amplitude decreases with the increase in resistivity of the ground, whereas it increases for an increase in dielectric constant value. When the displacement currents are ignored, the magnitude of amplitude of wave-tilt is reduced considerably. The altitude of measurement has minimal effect on the amplitude, but the phase changes appreciably in some cases.
