The resonant absorption of electromagnetic waves in an inhomogeneous and isotropic plasma without reflection is studied. The effect occurs when a p-polarized electromagnetic wave is incident on a plasma slab in which the density increases monotonically (parabolically) in the plasma-resonance region. The absorption itself is due to energy dissipation in this region, while the matching is due to the excitation of a mode which is approximately confined to this region. Specific examples are given of smooth, monotonic, reflector-free profiles from computer calculations. The possibility of generalizing the results to broader classes of media and fields is discussed.
