Design of carbon nanotube-based broadband radar absorber for ka-band frequency range

Abstract

The general principles of design and development of microwave absorbing materials are discussed and analysed in respect to 26–37 GHz frequency range (Ka-band). Dispersive composite materials based on carbon nanotubes in epoxy resin matrix are produced, and their electromagnetic responses are investigated in Ka-band. Both theoretical and experimental results demonstrate that presented composites may be used as compact effective absorbers in 26–37 GHz range.
