Abstract
Section titled âAbstractâWe report on imaging of microwave (MW) magnetic fields using a magnetometer\nbased on the electron spin of a nitrogen vacancy center in diamond. We\nquantitatively image the magnetic field generated by high frequency (GHz) MW\ncurrent with nanoscale resolution using a scanning probe technique. We\ndemonstrate a MW magnetic field sensitivity in the range of a few\nnT/$\sqrt{\text{Hz}}$, polarization selection and broadband capabilities under\nambient conditions and thereby establish the nitrogen vacancy center a\nversatile and high performance tool for the detection of MW fields. As a first\napplication of this scanning MW detector, we determine the MW current density\nin a stripline and demonstrate a MW current sensitivity of a few\nnA/$\sqrt{\text{Hz}}$\n
