Finite element modeling for microwave tomography

This paper presents a Finite Element Modelling for Microwave Imaging tomography based on edge basis functions. In particular a new technique is used to compute the antenna parameters. This novel procedure will provide a general method to enforce the excitation as a specific modal distribution, and to extract the voltage from the employed antenna. We show the model for the Microwave Imaging system including the antennas and we report a comparison between measured and simulated data.
