Abstract
Systems and apparatuses are disclosed for providing a uniform RF field and magnetic bias field to a nitrogen vacancy center diamond.
Claims21
A magnetic field sensor assembly comprising:
- four side radio frequency (RF) elements, each side RF element comprising an RF connection;
- four side RF feed cables operably connected to one of the four side RF elements such that each side RF element is connected to one RF feed cable that provides a feed signal to the side RF element;
- a top RF element;
- a top RF element feed cable that provides a top RF feed signal to the top RF element;
- a bottom RF element;
- a bottom RF element feed cable that provides a bottom RF feed signal to the bottom RF element, wherein the four side RF side elements, the top RF element, and the bottom RF element are arranged in a cube formation;
- and
- a nitrogen-vacancy (NV) center diamond located within the cube formation, wherein the side RF elements, top RF element, and bottom RF element generate a microwave signal that is uniform over the NV center diamond, and wherein the side RF elements, top RF element, and bottom RF element generate a magnetic bias field to the NV center diamond.
