Frequency difference images. (a) Frequency difference images between 6 frequency pairs. The images are displayed for the full 180 mm × 180 mm size of the electrode array using a RGB colorbar between −15 uƱ and + 15 uƱ as is customary in admittivity images. Here we have displayed magnitude and phase images as they more clearly show the conductivity magnitude and phase change over frequency.
