             abstract = "Currently, the use of electro-electronic equipment has been 
                         growing, with the consequent increase in electromagnetic 
                         pollution, harmful to the environment and living beings. Materials 
                         can mitigate this type of problem, seeking to combine, whenever 
                         possible, lighter and corrosion-resistant materials, replacing 
                         metallic materials. The present work studied the electromagnetic 
                         behavior in the X-band (8.212.4 GHz) of polymeric composites based 
                         on a 3D-carbon structure, named reticulated vitreous carbon (RVC) 
                         and epoxy resin (EP). RVC samples with different porosities (10, 
                         30, 45, and 60 pores per inch, ppi) heat-treated at 1000 °C were 
                         used. Electrical conductivity measurements showed for the 3060 ppi 
                         RVC samples high electrical conductivity values (~ 12 × 102 S/m) 
                         and the CVR/epoxy composites show a more insulating behavior (~ 
                         0.11.4 × 101 S/m), due to the influence of the EP. The 
                         electromagnetic characterization showed the variation of the 
                         complex components of electrical permittivity and magnetic 
                         permeability as a function of the CVR porosity and, consequently, 
                         on the electromagnetic shielding (SE) behavior. SE values of up to 
                         \≈ 99.5% of incident radiation were obtained for the 60 
                         ppi-RVC/EP composite, which has a greater number of alveoli per 
                         inch and a greater number of carbon struts. It was determined that 
                         wave energy losses in the composites occurred primarily by 
                         absorption, followed by reflection. In summary, all composites 
                         showed good total SE values (15.825.2 dB), indicating their 
                         potential use in different applications.",
