Abstract

A piecewise-linear model of the Kramers-Kronig (K-K) relations has been used to analyze electromagnetic dispersion data on RF polymers and composites. This K-K analysis revealed that concrete knowledge about the complex low-frequency material dispersion is critical to the analysis and understanding of the microwave dispersion. Furthermore, and more practically, the confidence in the material dispersion measurements may be, to some degree, ascertained through use of the K-K relations.
