Abstract :
A novel imaging method for the permittivity distribution in biological tissues is presented. It allows for the simultaneous reconstruction of real and imaginary parts of the permittivity and is applicable to strong scatterers and media with losses as high as in most biological tissues. The method is based on the spectral expansion of the permittivity function in the material under test. Availability is demonstrated on simulation results using noiseless and noisy input data. The method showed excellent stability in all cases.
