Polarization conversion from an aluminized triangular grating in conical mountings

We investigate, experimentally and numerically, polarization conversion from an aluminized echelette grating in regions near the resonant excitation of surface plasmons. Particular attention is paid to the difference between curves of the zeroth order cross-polarization reflection coefficients Rsp a...
