Abstract

The broadband dielectric properties of tumorous and non-tumorous tissues were analyzed at the microwave, millimeter wave, and terahertz ranges. In-vitro measurements were obtained using the coaxial probe and dispersive Fourier transform spectroscopy. Both techniques were modified to yield the complex real and imaginary permittivity, absorption coefficient, and refractive index. The results reveal the characteristic signatures of breast tissues and display a significant difference in the electromagnetic response of tumorous and non-tumorous tissues.
