Three-Dimensional Microwave Holographic Imaging Employing Forward-Scattered Waves Only

Figure 6

Simulation examples in FEKO. The background has properties of 𝜀^b_𝑟=16 and 𝜎_b=0.5 S/m. Imaging is performed for (a) a single object with properties 𝜀^o_𝑟=32 and 𝜎_o=1 S/m, (b) two objects with properties 𝜀^o_𝑟=32 and 𝜎_o=1 S/m along the 𝑧-axis, (c) two objects with properties 𝜀^o_𝑟=48 and 𝜎_o=2 S/m along the 𝑥-axis embedded in a lower contrast medium with properties 𝜀^m_𝑟=32 and 𝜎_m=1 S/m, and (d) two X-shape objects with properties 𝜀^o_𝑟=32 and 𝜎_o=1 S/m. All dimensions are in mm.
