Skywave refers to electromagnetic (EM) waves propagating in the waveguide formed by the ionosphere and the Earth's lithosphere [].Due to the large contrast in the electrical property between the ionosphere and air and between the lithosphere and air, the EM waves are reflected back and forth between the ionosphere …
WebGround conductivity is an extremely important factor in determining the field strength and propagation of surface wave (ground wave) radio transmissions. Low frequency (30–300 kHz) and medium frequency (300–3000 kHz) radio transmissions are particularly reliant on good ground conductivity as their primary propagation is by surface wave.
