Transverse electric and magnetic components of field measurement for microwave breast cancer imaging

In this paper, the observation of scattered fields due to dipole and circular-loop antennas for illuminating the breast are investigated. The Transverse Magnetic (TM) and Transverse Electric (TE) components of scattered fields are examined for a numerical breast phantom over the frequency range of 3-7 GHz for both circular-loop and dipole antennas. Results obtain through simulations demonstrate the ability of the circular-loop antenna as transmitter for illuminating the object in a microwave tomography system.
