Experiments with surface plasmons on rough and sinusoidally corrugated surfaces of metals with quasi-free electrons are performed to study the changes of the dispersion relation. The result is that the eigenfrequency of the plasma oscillations is displaced and the damping is increased. The dependence of the displacement and of the damping on the height of the roughness is shown. The results are compared with calculated values.
