Abstract :
The use of Padé approximants is proposed to recast the perturbation theory series in rough surface scattering studies. It is shown that Padé approximants yield reasonable results for significantly larger root mean square (rms) heights and smaller correlation lengths than the truncated perturbation theory series.
