WebOct 1, 1995 · In order to investigate the applicability of effective medium theory to describe the optical prop- erties of this model rough interface, we fitted the cal- culated ellipsometric data with the Bruggeman EMA. Our conclusions are twofold. First, it is possible to fit the results of the bump model with the Bruggeman EMA.
