Summary: | Presents a resonant permittivity measurement method which works over a large microwave frequency domain with a very small volume sample of dielectric material. The cell is a helical resonator having many modes of resonance. Results concerning 2 catalysts - [SmLiO(sub2)](sub0.8)[CaO - MgO](sub0.2) and BaBiO(sub3) - which are used in the reaction of methane oxidation are given as a function of temperature and frequency to illustrate the correlation of both data sets and the differences in catalytic mechanisms.
