Hello all, Just wondering if someone can give me a brief explanation of Wood's anomaly with regards to optics. Many thanks! Answers and Replies Jan 9, 2009 #2 malawi_glenn. Science Advisor. Homework Helper. Gold Member. 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 studies have been dedicated to this problem, focusing mainly on the case of metallic gratings.
