Abstract

The purpose of this report is to summarize the characterization of a number of high-frequency solid, liquid, and semisolid tissue-equivalent materials, from 200 MHz to 20 GHz. Carbon black and liquid mixtures were studied, but were found to be unsuitable for matching both the real and imaginary parts of the permittivity. We found that agar and agarose-based materials produced stable materials whose real and imaginary parts of the permittivity exhibited the required dispersive characteristics and could be easily tuned to fit a specific application and over a given frequency range.
