10 February 1981 Planar Grating Diffraction: Multiwave Coupled-Wave Theory And Modal Theory
Author Affiliations +
General slanted planar gratings bounded by two different media, have been analyzed using a new rigorous coupled-wave approach. The analysis is unifying and is formulated in a simple matrix form easily implemented on a digital computer. Sample calculations for transmission, slanted, and reflection gratings are presented. This new approach is compared to the widely-used modal approach and to the approximate coupled-wave approaches. It is shown that, for the present coupled-wave approach, solutions are easily calculated for general slanted gratings whereas solutions using the modal approach are available only for unslanted (pure trans-mission) gratings.
