abstract = "In this manuscript, the electromagnetic wave absorption properties
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 < Ø1 <
250 \𝜇m and 425 \𝜇m < Ø2 < 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 µm and
porosity between 180 and 250 µm). 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.",
