Abstract

Cairns and Lashmore-Davies have recently expressed the associated energy flow in terms of a single parameter which involves eta and the partial derivations of omega-1 and omega-2. In this paper, a different, wave mechanical approach is used to obtain the same result. The process of linear mode conversion is discussed using the system LPSI = ideltaPSI/deltat, where L is a Hermitian operator. The degeneracy of plasma modes, and their coupling by warm plasma corrections in an inhomogeneous plasma, is dealt with using first order perturbation theory. Simple coupled first order differential equations for the wave amplitudes follow, which can be integrated directly. The calculated energy flow reproduces the expression that is obtained from the theory of Cairns and Lashmore-Davies.
