Abstract
The rigorous coupled wave method and the rigorous modal method are fre quently used to analyze lamellar, multilevel gratings. Both methods re sult in a system of linear equations that has to be solved to obtain t he transmitted and reflected amplitudes. An algorithm is presented to increase the numerical stability in the evaluation of these amplitudes . Numerical examples and comparisons with recently published results a re given.
