Abstract
An inductor comprises a quasi-toroidal conductive envelope having a discontinuity across which alternating voltage may be applied. The inductor may comprise a plurality of interrupted turns connected in parallel or may be formed by a continuous conductive shell. The cross-section of the envelope may be circular, rectangular, or shaped in any other desired manner. Capacitive elements may be arranged within the interior of the device to form a resonator.
Claims4
A resonator comprising a quasi-toroidal inductive envelope formed by a continuous conductive shell having a discontinuity in the surface near the axis thereof, the discontinuity being small in comparison with the perimeter of the shell taken along a cross-section through the axis of the quasi-toroidal envelope, a first terminal in the form of a cylinder of small radius compared with the dimensions of the shell concentric with the axis of the shell and extending axially away from and connected to one side of the discontinuity, a second terminal in the form of a conductor lying generally along the axis of the shell electrically connected to and extending axially from the other side of said discontinuity to the interior of said cylinder and insulated therefrom, thereby to form a co-axial cable termination for said resonator, and a capacitor formed between the first and second terminals in the vicinity of the discontinuity of said surface, thereby to form a parallel resonant circuit.
