In this paper, COMSOL Multiphysics software is utilized as a finite element forward solver to obtain the electromagnetic fields at the receiving antennas while the breast is illuminated by one antenna in the array. Geometry consists of coronal slices of the 3-D breast. Simulations are done by a MATLAB code which runs COMSOL finite element solver and collects the data at the receiving antennas at each operating frequency for any radiating antenna. The results are then compared with the output of an FDFD solver. Predicted fields can be used in an iterative inversion algorithm which reconstructs the tumor and other unknown boundaries.
