Abstract: A fast-wave pulse in a simple, cold, inhomogeneous MHD model plasma isconstructed by Fourier superposition over frequency of harmonic waves that aresingular at their respective Alfven resonances. The pulse partially reflectsbefore reaching the resonance layer, but also partially tunnels through to itto mode convert to an Alfven wave. The exact absorption-conversion coefficientfor the pulse is shown to be given precisely by a function of transversewavenumber tabulated in Paper I of this sequence, and to be independent offrequency and pulse width.
