Sensitivity of image reconstructions to background permittivity for Example 4. (a), (c), (e), (g), and (i) and (b), (d), (f), (h), and (j) Relative permittivity and conductivity, respectively. The scattered field data was generated in HFSS in a background of (21, 0.475). The reconstructions are done with assumed background relative permittivities of {20, 20.5, 21, 21.5, 22} for (a) and (b), (c) and (d), (e) and (f), (g) and (h) and (i) and (j), respectively. The recovered contrasts of the sphere oscillate about the background.
