Abstract :
A 60-mm-diameter cylindrical cavity resonator used for high-accuracy permittivity measurements on low-loss materials is described. The cavity operates at X-band in the TE/sub 01p/ mode and is of the mode-filtered type with helically wound walls. Measurement data on representative dielectric materials are presented together with an uncertainty analysis.<>
