Abstract :
The presence of small sample insertion holes in a cylindrical cavity produces a shift in the complex resonance frequency of the cavity. A mathematical model is proposed to compute the shift when the cavity oscillates in an axially symmetric TM/sub 0mp/ mode The treatment applies to samples with arbitrary complex permittivity. The model is compared to other treatments and checked against measured results.<>
