Based on the Rayleigh-Ritz method and an eigenmode expansion of the wake function, we devised a semi-analytical description of the wakefield inside a dielectrically lined rectangular waveguide. We implemented this method and employed it to determine the geometrical parameters of a dedicated dechirper for the use at the light source ELBE in Dresden-Rossendorf. In 2016, a construction team at ELBE built a dielectrically lined rectangular waveguide with the given geometry. Subsequently, we carried out experiments with this prototype at ELBE. In this contribution, we present the model structure and compare the results obtained semi-analytically with experimental data.
