Microwave imaging is an efficient technique to non-invasively visualizing dielectric properties of non-metallic bodies. One potential of the technique is the high contrast in dielectric properties between biological tissues. In the 80’s, Supélec developed a 2.45 GHz planar microwave camera, in the 90’s the group developed algorithms for quantitative microwave imaging. The purpose of this study is to investigate the capability of these existing materials, or an extended version of them, in terms of quantitative imaging of high-contrast inhomogeneous object for application of breast cancer detection. A two-dimensional formalization is considered to be followed up with future three-dimensional investigations.
