Time difference images of the imaginary component of admittance. (a) Time difference imaginary trans-admittance maps for the testing objects obtained at 10 different frequencies. 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. (b) and (c) Admittance of the cross section over the center of the testing objects at each frequency.
