Sparse localization of breast tumors using quasi-TE polarized antennas

We develop a three-dimensional (3D) sparse algorithm for localization of breast tumors, using an antenna array and signal processing. Assuming that the prior-knowledge of the breast tissue distribution is available, we develop a model in which the trans-polarization is fully taken into account. By considering various array configurations, we also investigate the robustness of the algorithm to the inaccuracies in the assumed electromagnetic parameters of the breast.
