ABSTRACT:
A tuning assembly is disclosed for selectively oscillating the frequency of an electromagnetic field within a hermetically sealed device, which device includes a rigid, hermetically sealed housing, apparatus for generating the electromagnetic field therewithin, and elements for defining a cavity within the housing for establishing the frequency of the electromagnetic field. The tuning assembly includes electrically conductive members mounted for linear movement within the cavity to selectively vary the volume of the cavity to oscillate the established frequency. Elements disposed within the rigid housing are provided for mounting the electrically conductive members, and are adapted for oscillatory movement at a pre-determined mechanical resonant frequency to move the electrically conductive members in the described linear manner. Finally, a power source is provided exterior to the rigid housing and is magnetically coupled to the mounting elements for exciting the mounting elements.
