Antenna Modeling and Reconstruction Accuracy of Time Domain-Based Image Reconstruction in Microwave Tomography

Figure 10

Reconstructions of the two target model from Figures 9(a) and 9(b). Here (a) and (b) show the reconstructed result when replacing the RVS feed of the monopole with a hard source. In (c) and (d) the results when removing the wire model of the antenna and using only a hard source as the transmitter model, and on the receiver side the field was directly sampled in the corresponding grid point.

(a) Thin-wire with hard feed, 𝜖_𝑟, 𝛿=0.54

(b) Thin-wire with hard feed, 𝜎, 𝛿=30

(c) Hard source transmitter, 𝜖_𝑟, 𝛿=0.58

(d) Hard source transmitter, 𝜎, 𝛿=87
