Tunneling versus absorption in X‐mode transmission through cyclotron layers

Although proven analytically from mode conversion theory that the transmission coefficient through a cyclotron harmonic layer is independent of absorption, the result seems so nonintuitive that another way of seeing this result is given.

Description
Summary:Although proven analytically from mode conversion theory that the transmission coefficient through a cyclotron harmonic layer is independent of absorption, the result seems so nonintuitive that another way of seeing this result is given. In this paper, the transmission coefficient is deduced from the usual integral of the imaginary part of k over the layer, both with and without absorption. The fact that these both give exactly the same result, which agrees with the analytical result from mode conversion theory, shows that the absorption plays no role whatsoever in the transmission coefficient.
