Simulation study on compensating group delay distortion based on material dispersion

In this study, we investigate the group delay distortion of a signal due to the presence of dispersion in transmission systems, and propose an approach to eliminate the distortion by dispersion compensation based on engineered material dispersion. We demonstrate that utilizing the anomalous frequency response of a dispersive material, envelope distortion of a signal passing through a given transmission system can be compensated, theoretical analysis and full-wave simulation agreeing well with each other.
