a Background-corrected spectra of pure ITO (green line) and a single NV through the ITO strip line (blue line) and without ITO on top (orange line). The intensity of each spectra is normalised by the peak value of the spectra of a single NV without ITO on top. b Measured Rabi frequencies of single NVs with different distances to the strip line. Each point represents a single NV in [111] (blue) or [\(\overline{11}1\)] (green) direction. The solid lines are Comsol simulation fits with Eqs. (1, 2) and the shaded areas represent the standard deviation error of the fit parameters \(a\) and \(b\). The centre of the strip line is located at a \(y\) position of 0 μm
