Abstract
The accuracy of permittivity measurement using an open resonator has been studied. The error in the determination of permittivity arising from the imperfection of beam-wave theory is estimated. It is further shown that, by an improved method of analysing the experimental results, the effect of the imperfection in the theory is reduced and a great improvement in accuracy can be obtained.Keywords
