Abstract

Angular reflection spectra of 1D arrays of grooves in a metal film in the Kretschmann configuration has been studied numerically. The case of a wave incident in the plane parallel to the grooves has been considered. For the s-polarized incident wave two types of features in the reflection spectra occur: the first is associated with excitation of channel plasmons in every single groove of the array and the second is the Wood anomaly-like feature.
