Abstract
A magnetic field sensor assembly includes a first radio frequency (RF) element; a second RF element; an RF feed cable operably connected to the first RF element and the second RF element that provides an RF signal to the first RF element and the second RF element; and a magneto-optical defect center material located between the first RF element and the second RF element. The first RF element and the second RF element generate a microwave signal that is uniform over the magneto-optical defect center material. The magneto-optical defect center material may be a nitrogen-vacancy center diamond.
