Non-Resonant Mode-Coupling Model of ICRF Heating

摘要

The theory of non-resonant coupling of a well-defined mode to a quasimode is generalized to include the effects of weak inhomogeneity. The resulting formalism is used to determine an analytic form for the transmission coefficient of the fast wave in ICRF heating; this entails the solution of only a first order differential equation. The analytical results, valid for arbitrary k/sub parallel/, are compared with numerical results of usual models involving higher-order differential equations, and found to be in excellent agreement.
