Ground Wave Propagation: Factors, Frequency Range & Uses

Lower frequency (between 30 and 3,000 kHz) vertically polarized radio waves can travel as surface waves following the contour of the Earth; this is called ground wave propagation. In this mode the radio wave propagates by interacting with the conductive surface of the Earth. The wave "clings" to the surface and thus follows the curv… Webto E of the incident wave causes vibrating electrons to follow elliptic paths. The new E (=F/Q) will have two components, one parallel and the other perpendic-ular to E of the wave. Thus, the polarization of E will be rotated by 90 in space with respect to the incident wave. Since some of the portions of such paths have digimon next order how to exe
