A More Efficient Rigorous Coupled-Wave Analysis Algorithm

Mathematics in Industry, 2006
We present a modification of a well-known mathematical model based on the Rigorous Coupled-Wave Analysis (RCWA) that can be used to solve optical diffraction problems on periodic structures (both 1-D and 2-D gratings with approximated layer-structure). The algorithm calculates the reflected and transmitted field which in turn determine the diffraction ...

Rigorous coupled-wave analysis of planar-grating diffraction

Journal of the Optical Society of America, 1981
A rigorous coupled-wave approach is used to analyze diffraction by general planar gratings bounded by two different media. The grating fringes may have any orientation (slanted or unslanted) with respect to the grating surfaces. The analysis is based on a state-variables representation and results in a unifying, easily computer-implementable matrix ...

Algorithm for the rigorous coupled-wave analysis of grating diffraction

Journal of the Optical Society of America A: Optics and Image Science, and Vision, 1994
Diffraction of light by periodic gratings is analyzed with a characteristic-matrix formalism based on a rigorous coupled-wave approach. This formalism is particularly convenient for modeling the diffraction by nonuniform periodic structures. In order to overcome numerical difficulties that are due to inhomogeneous eigenmodes, we propose a new algorithm

Rigorous coupled-wave analysis of pure reflection gratings

Journal of the Optical Society of America, 1983
Rigorous coupled-wave analysis is shown to be valid for a pure reflection grating The analysis is extended to take into consideration an arbitrary phase of the sinusoidal modulation of the pure reflection grating’s dielectric constant The correct method of computing the diffraction efficiencies is presented, and results obtained with the extended and ...

Study of eigenvalue behavior in rigorous coupled-wave analysis (RCWA)

OSA Annual Meeting, 1993
Rigorous Coupled Wave Analysis (RCWA) is a popular method for the computational analysis of diffraction gratings due to its simplicity, rigor and the ease of implementation.
