Rayleigh-wood anomalies

WebThe Rayleigh Wood anomalies refer to an unexpected repartition of the electromagnetic energy between the several interference orders of the light emerging from a grating. Since Hessel and Oliner (Appl. Opt. 4, 1275-1297 (1965)), several … WebRayleigh–Wood anomaly,14 found in metallic gratings with relatively wide slits. Although the Rayleigh–Wood anomaly is usually associated with the resonant excitation of an SP, the same effect is also present whenever there exists a sur-face mode, such as a slab waveguide mode in close proxim-ity to the grating.5
