The authors study propagation characteristics of gaussian radio beams through the ionosphere. The radio beams ohmically heat electrons, which then tend to diffuse away. The plasma duct which is formed tends to focus the radio wave field, resulting in a positive feedback situation. The authors derive equations which relate the relative focusing, amplification factor, amd width of the resulting spike to wave freqency, plasma frequency, sound speed, and electron oscillatory velocity.
