Abstract (en)
[origin: WO8502265A1] Low density compositions containing colloidal-size particulates of an ELM absorber such as Fe3O4 and a particulate of an ELM attenuator such as carbonyl iron dispersed in a dielectric matrix such as a styrene/butyl acrylate copolymer provide improved absorption of electromagnetic radiations.
