a Spatial mapping of the THz near-field scattering amplitude s measured on a junction area in a 2D false color plot. b THz near-field image of the same area in a after rotating the sample 180 degrees in the sample plane. c A simultaneously acquired AFM topography image of the same region in b. d, e A typical time-resolved THz near-field waveform measured on the sample and its Fourier transformed spectrum. f, g THz near-field contrast images of two additional Josephson junctions.
