Dielectric spectroscopy of breast tissue — Measurement and permittivity models

The knowledge of dielectric properties of breast tissue in a wide frequency range of 0.1 to 20 GHz forms the foundation for a variety of novel microwave techniques for breast cancer detection [1,2,3]. In collaboration, the Universities of Calgary and Wisconsin-Madison are building an extensive database of breast tissue dielectric properties for further advances of microwave technologies for breast cancer detection and treatment [1,5,7].
