Abstract :
The refractive index, absorption coefficient, complex real and imaginary permittivity, and loss tangent of normal (non-tumorous) and tumorous breast tissues have been obtained from 0.2 to 0.9 THz. Dispersive Fourier transform spectroscopy was utilized to acquire the broadband millimeter and submillimeter wave dielectric properties and unique resonance signatures of breast tissues for the first time. Results indicate a significant difference in the electrical characteristics of tumorous and non-tumorous breast tissues.
