Abstract
A resonator for a high frequency electromagnetic oscillator is disclosed. The resonator includes a hollow cylinder formed of a material having a low dielectric constant and a dielectric wire formed of a material having a higher dielectric constant and located within the cylinder. The dielectric wire has a length similar to that of an open half-wire coaxial resonator or a whole number of multiples thereof. The dimensions of the wire are chosen as a function of the dielectric constants of the hollow cylinder in the dielectric wire as well as the desired resonant frequency such that a standing TEM-wave is established in the hollow cylinder and a E.sub.0m -wave (circular magnetic field, m=1,2,3 . . . ) is established in said wire.
