a Agar phantoms were based on a sphere of radius rt = 2 cm (dotted line) located at the center of a cylinder of diameter d = 10 cm and height H = 11 cm. Note that a circular fragment of the cylinder has been removed to facilitate the observation of the central sphere. b Experimental setup used to electrically characterize each phantom, including an RF applicator (active electrode) inserted into the center of the sphere doped with NaCl or AuNPs. The entire phantom was surrounded by a 2-mm-thick aluminum foil that acted as a dispersive electrode
