Abstract
A study of the electrodynamical properties of open coaxial cylindrical resonators using a partially conical inner rod is made along with exp erimental verification. On the basis of a geometrical criterion for th e occurrence of high-Q resonances, it turns out to be possible to disc riminate certain classes of TE modes by keeping to a minimum value the ir diffration Q factors. In particular, for an especially designed cav ity only TE(0.2) and TE(1.3) modes appear to have strong resonance in the 6 - 14GHz range as a result of the action of the coaxial insert.
