Abstract

A new hybrid material solution has been developed for electromagnetic waves absorption based on a hierarchical architecture involving carbon nanotubes reinforced polymer foam inserted inside a metallic honeycomb structure. The honeycomb acts like a waveguide and improves the absorption up to 95% of the incident power near the cut-off frequency and delivers a high level of absorption above. Moreover, the honeycomb improves the mechanical performance of the foam and allows for thermal dissipation.
