WebApr 26, 2024 · The red plot is measured differential TDR from [3]. When core and prepreg Dk from Dk/Df tables were used along with a non-causal roughness model in the simulation, the blue plot shows an overestimate for impedance. When Dkeff from Equation 2, and a non-causal roughness model was used in the simulation, the pink plot shows an … WebNov 19, 2024 · The first and the easiest one is to right-click on the selected TDR file.
