Fig. 9. Comparison of the electric images of different objects. (A) Modulation of
metal cubes (red squares) and metal spheres (blue circles) in the horizontal
plane. Each point represents the mean of three measurements. (B) The same
comparison in the medial plane. (C) Comparison of the modulation resulting
from a plastic cube (red squares) and a plastic sphere (blue circles). (D) The
same comparison in the medial plane.
