Abstract:

Rays of the Z-mode have been traced through tilted layers of the ionosphere and it was found that tilted layers can explain the occasional appearance of Z-mode echoes in ionograms. It was also found that the type of tilted layer determines the range of frequencies over which Z-mode echoes are received. This theoretical result agrees with certain ionograms which show both an intense spread-F effect in the ordinary and extraordinary echoes and a clear Z-mode echo over a limited spectral range. A method has also been developed to take into account the existence of a coupling cone around the direction of the magnetic field at X 1 without going through the complicated procedure of a full wave solution.
