This paper will address the specific material relationships necessary to produce consistently causal and accurate electrical component models. The need for causal component models will be highlighted by showing the types of digital waveforms that result from simulating structures non-causally. A brief discussion of causal relationships that must be maintained between conductor resistance and inductance as well as dielectric conductance and capacitance will be given. Ultimately, a measurement technique will be outlined for producing causal permittivity data that is accurate across a broad frequency band. Final model data will be provided, verifying the accuracy and causality of the method.
