COMPOSITE MATERIALS BASED ON carbon black and hydrogels used for hidden objects from technical intelligence service

Abstract

The research results of reflection and transmission coefficients of flexible composite materials based on carbon black and hydrogels in the range 8…12 GHz are presented. Spectral and polarization properties of carbon materials in the visible wavelength range (450 ... 940 nm) were analyzed. Recommendations for using composite materials based on carbon black and hydrogels for hiding objects on different background were formed.
