The broadband and tunable high-performance microwave absorption properties of an ultralight and highly compressible graphene foam (GF) are investigated. Simply via physical compression, the microwave absorption performance can be tuned. The qualified bandwidth coverage of 93.8% (60.5 GHz/64.5 GHz) is achieved for the GF under 90% compressive strain (1.0 mm thickness). This mainly because of the 3D conductive network.read more

Microwave absorbing property optimization of starlike ZnO/reduced graphene oxide doped by ZnO nanocrystal composites.
TL;DR: The enhanced microwave absorption properties can be ascribed to the starlike ZnO, which hinder the agglomeration of RGO, as well as the ZnNO nanocrystals, effectively improving the interface of the heterostructure and the impedance matching of R GO.

Microwave Absorption Enhancement and Complex Permittivity and Permeability of Fe Encapsulated within Carbon Nanotubes
TL;DR: In this paper, the absorption properties of CNT/crystalline Fe nanocomposites have been investigated and it was shown that the absorption property is due to the confinement of crystalline Fe in carbon nanoshells, deriving mainly from magnetic rather than electric effects.
