Investigations into optimum characteristics for the coupling medium in UWB breast cancer imaging systems
TL;DR: In this paper, a theoretical analysis supported by computer simulations is conducted to work out the optimal characteristics of the coupling medium for UWB breast cancer detection, which is based on two fundamental properties: tumours have higher water content and hence a higher dielectric constant compared with the normal breast tissues, which are mainly fat.

The Information Carried by Scattered Waves: Near-Field and Nonasymptotic Regimes
TL;DR: In this paper, the number of spatial degrees of freedom of the field radiated in a two-dimensional setting by a time-harmonic, arbitrary square-integrable current density and in the presence of a random distribution of scattering elements is determined.
