Extraction of eps(f) and tand(f) for BT Insulator up to 30 GHz Using the Short-Pulse Propagation Technique

The self- consistent frequency-dependent dielectric constant, er(f), and dielectric loss, tand(f), are determined over the range 2 to 30 GHz using a short-pulse propagation technique and an iterative extraction based on a rational function expansion. Simulations of signal propagation on printed circuit board wiring using transmission-line models based on these results show very good agreement with measured step and pulse time-domain excitations.
