A second-order differential equation for the ion-cyclotron fast wave propagating in a hot, two ion species plasma is obtained. The equation includes the effects of both minority fundamental and majority second harmonic cyclotron damping. The approximation is based upon replacing the coupling to the ion Bernstein wave by a modified propagation description of the fast wave. For the case of perpendicular propagation, the second order equation reduces to the Budden equation giving the well known transmission coefficient for both two ion hybrid and second harmonic resonance. The solutions of the second order equation as a function of n/sub parallel/ give transmission and reflection coefficients which agree very well with the results based on models using higher order differential equations.
