A new model for dielectric loss, suitable for time domain modeling of printed circuit boards, is proposed. The model is based on a physical relaxation model. Complete time domain modeling of skin effect and dielectric losses in FR-4 boards are demonstrated and experimentally verified. Finally, the developed model is used to predict that FR-4 boards are useful for data rates up to 10 Gb/s.
