Abstract
Large Goos-Hanchen effects are isolated for reflection an a metallic gratin g. These shifts occur in the vicinity of Wood anomalies. Depending on the n ature of the anomaly, these displacements are found to be either positive o r, contrary to the usual GH effect, clearly negative. Those shifts, associa ted with forward and backward leaky surface waves, are as large as plus or minus tens of wavelengths for a classic metallic grating. (C) 2001 Optical Society of America.
