Whistler leakage from plasma waveguides
Abstract
Whistlers are shown to always leak out of high-density waveguides according to results by Stenzel (1976). Equations are derived which give a quantitative description of the leakage such as wave damping rate, and lead to an explanation for effects observed in other experiments. It is found that waveguide propagation cannot occur in channels with a high density if u is not less than 1/2 (where u is the ratio of whistler frequency to electron gyrofrequency), and low-density channels may be ideal waveguides for all values of u.
