We present the calculation of the absorption of S- and P-polarized light at a lossy interface for which the density gradient has a scale length less than the wavelength of the incident radiation. Recent experimental measurements of the absorption of a short laser pulse as a function of intensity can be satisfactorily modeled by a combination of changing material collisionality and increasing scale length of the density gradient at the interface.
