This paper presents a detailed comparison of the results of a 3D FDTD numerical model and experimental measurements of the antenna response of a microwave tomography system. The FDTD algorithm uses the thin-wire approximation to model the antenna structure and a resistive voltage source is used to excite the signal. The algorithm was validated against experimental data obtained for an array of monopole...
This letter presents a detailed study of a microwave tomography system using 3-D finite-difference time-domain methods (FDTDs). The algorithm, which uses a subcell model in form of the thin-wire approximation to model wire antennas, has been validated numerically using published numerical electromagnetic code (NEC) data for dipole antennas, and experimentally by comparing with measurements obtained...
