Abstract
A housing for coupling to a loop gap resonator (LGR) includes an interior cavity in which the LGR is disposed therein. The LGR is attached to the housing by at least one mounting bracket, which fixes the LGR in the interior cavity. Additionally, the interior cavity includes a separation region between the cavity walls and the LGR. The widths of each mounting bracket and the width of the separation region is determined in order to support a uniform electromagnetic field inside the LGR.
Claims20
A device, comprising:
- a housing coupled to a loop gap resonator (LGR), wherein the LGR includes an inner cavity and is configured to support an electromagnetic field in the inner cavity,
- wherein the housing comprises:
- an exterior, and
- an interior, wherein the interior comprises an interior cavity in which the LGR is disposed therein,
- wherein the housing comprises at least one mounting bracket protruding into the interior cavity, wherein the at least one mounting bracket has a first width and is configured to fix the LGR in the interior cavity of the housing,
- wherein the LGR is fixed by the at least one mounting bracket so that there exists a separation region between an outer edge of the LGR and an inner edge of the housing, wherein the separation region has a second width,
- wherein based on the first width of the at least one mounting bracket, and the second width of the separation region, an electromagnetic field of substantially uniform phase and amplitude is provided in the inner cavity of the LGR.

A system, comprising:
- a signal generator configured to couple an electromagnetic signal in a loop gap resonator (LGR), wherein the LGR includes an inner cavity and is configured to receive the electromagnetic signal and to generate an electromagnetic field in the inner cavity;
- a housing coupled to the LGR, wherein the housing comprises:
- an exterior, and
- an interior, wherein the interior comprises an interior cavity in which the LGR is disposed therein,
- wherein the housing comprises at least one mounting bracket protruding into the interior cavity, wherein the at least one mounting bracket has a first width and is configured to fix the LGR in the interior cavity of the housing,
- wherein the LGR is fixed by the at least one mounting bracket so that there exists a separation region between an outer edge of the LGR and an inner edge of the housing, wherein the separation region has a second width,
- wherein based on the first width of the at least one mounting bracket, and the second width of the separation region, an electromagnetic field of substantially uniform phase and amplitude is provided in the inner cavity of the LGR.
4 more elements
A method, comprising:
- determining dimensions of at least one mounting bracket and a separation region, wherein the dimensions of the at least one mounting bracket include a first width, wherein the dimensions of the separation region include a second width;
- fabricating the at least one mounting bracket, wherein the at least one mounting bracket is coupled to a housing and protrudes into an interior cavity of the housing;
- coupling a loop gap resonator (LGR) to the at least one mounting bracket, wherein the LGR includes an inner cavity and is configured to generate an electromagnetic field in a region of free space in the inner cavity, wherein the LGR is disposed into the interior cavity of the housing such that the second width of the separation region separates the LGR from the housing;
- inputting an electromagnetic signal into the LGR;
- and
- exciting a desired electromagnetic mode at a resonance frequency in the inner cavity of the LGR from the electromagnetic signal.
