Abstract
Dielectric lamellar transmission gratings with several grooves in a period have become well established as array generators in free-space digital optical systems. The performance of these elements as they enter the local resonance domain has previously been analyzed. A modal algorithm is developed for perfectly conducting Dammmann gratings. The method is first applied to the abalysis of the scalar theoretic designs in a local resonance domain. Reflective resonance domain Dammann gratings are then designed, and their sensitivity to errors in fabrication and reconstruction is analyzed.
