Using the thin-wire approximation with resistive voltage sources (RVS), a realistic FDTD model is created for the transmitting and receiving antennas. To verify the algorithm, image reconstruction is made from experimental data using a cylindrical test object made of sunflower oil. In the results, successful image reconstruction has been shown, indicating that the FDTD model is applicable. For comparison, a reconstruction with a two-dimensional (2D) version of the algorithm was made. A significant increase in accuracy of the reconstructed object was seen for the 3D version.Keywords: 3D image reconstruction; Antenna modeling; Experimental data; FDTD model; Microwave imaging; Microwave tomography; Reconstructed objects; Resistive voltage; Sunflower oil; Test object; Three-dimensional (3D) image reconstruction; Algorithms; Finite differ Antenna modeling; Finite-difference time-domain (FDTD) methods; Microwave imaging; Microwave measurements; Tomography200910.1109/LAWP.2009.20390322016-02-24
