ABSTRACT:
In accordance with the principles of the present invention, a resonator puck is provided with one or more vertical and/or horizontal, radial slits that improve the quality factor, Q, of circuits constructed from the resonators. In some embodiments of the invention, the surfaces of the resonators that define the slit are left relatively rough and may even contact each other such that the slit is not of uniform thickness, but essentially comprises a plurality of pockets between the two portions of the resonator.
