We dedicate this paper to the memory of Ilya Mikhailovich
Lifshitz on the occasion of his 100th birthday. He was a brilliant physicist and a great human being, whom
one of us (A.A.M.) had the pleasure of knowing.
The research of I.S. was supported in part by The Research
Council of Norway Contract No. 216699.

A periodically corrugated interface between vacuum and a high-index dielectric medium supports a p-polarized leaky surface electromagnetic wave whose sagittal plane is perpendicular to the generators of the interface. This wave is bound to the surface in the vacuum region, but radiates into the high-index dielectric medium. We study the excitation of this wave by p-polarized light incident from a prism on whose planar base the highindex dielectric medium in the form of a film is bonded. The unilluminated surface of the film is periodically corrugated, and is in contact with vacuum. Peaks and dips in the dependence of several low-order diffraction efficiencies on the angle of incidence (Wood anomalies) are the signatures of the excitation of the surface wave.
