We obtain the optical response of a multilayered system in which the interfaces have a common periodicity but arbitrary shape by extending a published method previously restricted to interfaces with identical profiles [ J. Opt. Soc. Am. 72, 839 ( 1982)]. Numerical comparisons with other modeling results for grating systems are presented that show the effectiveness of the new method.
