Abstract
In this work, we experimentally studied sharp plasmonic resonance on gold gratings in both amplitude and phase domains using a spectroscopic ellipsometry technique. We used numerical and analytical models to analyze the phase delay of TM and TE waves under a surface plasmon excitation condition, and the calculated result fits well with the experimental observations. In addition, the ellipsometry method used here provides an important tool to characterize the phase information in plasmonic and metamaterial devices.
