<span>For materials characterization, several methods have been developed. Most of them need a sample to be machined prior testing process. Hence, they are destructive and cannot used for in-situ radar absorbing coatings testing. This requires employing suitable measurement technique extract their electromagnetic properties quickly accurately. In this paper, the swept frequency probe refl...

A composite material based on ellipsoidal inclusions distributed in a bonding medium is considered. formula obtained for calculating the effective dielectric constant of such material, taking into account presence layer binder inclusions, which prevents their direct contact. It shown that calculated values correspond to experimental sections conductive fibers. Keywords: radar absorbing structur...

The thesis addresses time-domain inverse electromagnetic scattering for determining unknown characteristics of an object from observations of the scattered field. Applications include non-destructive characterization of media and optimization of material properties, for example the design of radar absorbing materials. Another interesting application is the parameter optimization of subcell mode...
