摘要
Suitable correction factors are incorporated in the measurement of shift in resonance frequency and full width at half-maximum in the cavity perturbation technique when the sample is inserted partially into the cavity. The present approach is observed to be more accurate compared to the available theories and it does not have limitations concerning the shape of the sample. Several standard samples are taken for the present measurement and compared with the full insertion method. Some of the samples are partially inserted into the cavity step by step and the experimental results are compared with the present approach and that of Lehndroff.
