Abstract
A quantum-based sensor includes a hollow electromagnetic (EM) waveguide having non-metallic layers and external metallic layers. The hollow EM waveguide encloses a gas having a pressure that is less than a threshold pressure, and all interior surfaces of the hollow EM waveguide in contact with the gas are non-metallic.
Claims22
An apparatus, comprising:
- an electromagnetic (EM) waveguide including a container having a cavity configurable to hold a gas and prevent the gas from being in contact with a metal;
- and
- first and second metallic layers exterior to and on opposing first and second sides of the cavity.
A circuit, comprising:
- a container holding a gas, in which the gas is not in contact with a metal;
- a control circuit having an antenna, the antenna configurable to interface with the container, and the control circuit is configurable to:
- provide a first signal to the gas in the container via the antenna;
- receive a second signal from the gas in the container in response to the first signal via the antenna;
- and
- generate a third signal based on the second signal.
3 more elements
A method, comprising:
- combining a first set of layers and a second set of layers in presence of a gas to form an EM waveguide holding the gas, wherein the gas in the container is not in contact with a metal, in which the first set of layers includes a first metallic layer, the second set of layers includes a second metallic layer, and the first metallic layer opposes the second metallic layer;
- and
- aligning an electromagnetic (EM) opening of the EM waveguide with an antenna of a control circuit.
An apparatus, comprising:
- an EM waveguide including a container configurable to hold a gas, in which an entirety of internal surfaces of the container is non-metallic.
