Meander delay line challenge problem: a comparison using FDTD, FEM and MoM

Full-wave finite-difference time-domain (FDTD) and a simplified 1Dfinite-difference time-domain technique using the multi-conductor transmission line equations were applied to a delay line to determine its propagation characteristics. The output voltage waveform was calculated using the two methods and the results were compared to those obtained by two commercially available finite-element codes and two method-of-moment codes. Radiated fields from this structure are also included for the different numerical approaches.
