                         of sustainable porous carbon composites were evaluated over the 
                         X-band frequency range (8.2 12.4 GHz). The porous carbon material 
                         was made from the byproduct of cellulose production and was used 
                         as additive on the development of radar absorbing material (RAM) 
                         composites. These porous carbon materials have different 
                         characteristics, such as porosity size (180 \𝜇m < 1 < 
                         250 \𝜇m and 425 \𝜇m < 2 < 500 \𝜇m) and 
                         particle size (\ϕ1 < 250 \𝜇m and 250 \𝜇m < 
                         \ϕ2 < 425 \𝜇m). Composite materials were also 
                         studied as frequency selective surface (FSS) structures. It was 
                         shown how complex permittivity and reflection loss (RL) can be 
                         manipulated over the frequency range using FSS structure. While 
                         regular RAM presented RL of 19 dB at ~11.8 GHz, FSS structure 
                         presented a RL of 19 dB shifted to 12.4 GHz regarding the same 
                         carbon porous material (with particles between 250 and 425 m and 
                         porosity between 180 and 250 m). It was demonstrated here the 
                         potential use of sustainable porous carbon as RAM, and how FSS 
                         structure can be used to tune the frequency of the RL maximum 
                         peak.",
