Abstract
The present invention is, in one aspect, a radio frequency source, comprising a gyromagnetic precession oscillator. In a second aspect, the gyromagnetic precession oscillator comprises a closed, non-magnetic, cylindrical outer conductor defining a cavity therein; an axial field solenoid wound about the outer conductor; a non-magnetic, cylindrical inner conductor disposed within the cavity and coaxially aligned with the outer conductor; a plurality of cylindrical ferrite precessors, each defining a respective bore through which the inner conductor runs; a plurality of dividers disposed within and defining a resonant chamber in the cavity; and a dielectric material filling the cavity. In a third aspect, the radio frequency source is actively tunable. In a fourth aspect, the radio frequency source that is tunable pulse-to-pulse.
