This paper provides a novel strategy for the extrapolation and regularization of low frequency data of low-loss or lossless structures, based on asymptotic modal trajectories. The proposed data-driven strategy is intended as a fundamental pre-processing step to obtain a full-bandwidth reliable macromodel to be used in transient simulations, providing full control of the low-frequency and DC behavior of the system.
