The power reflection coefficient for D(H), DT({sup 3}He), and D ({sup 3}He) ion cyclotron heating is found in closed form. The fast wave equation previously solved numerically is solved by a slowly varying amplitude expansion about the Budden equation asymptotics. The coupling between the fast Alfven wave and the ion Bernstein wave is described by this formalism. The dissipation associated with the ion cyclotron resonance is accounted for by the slow variation. Validity criteria for this method are presented.
