Comparing a time-domain and frequency-domain based algorithm in microwave tomography

A comparison of two different reconstruction algorithms developed for microwave tomographic imaging has been performed. One of the algorithm is an FDTD algorithm and the other one is an FEM-based one. Simulated S-parameters for a 16-antenna system are generated for a numerical phantom, which are then used to solve the inverse problem. It is shown that both algorithms could use the generated S-parameters to successfully reconstruct the studied phantoms
