             abstract = "Radar Absorbing Materials (RAMs) are composite materials able to 
                         attenuate the reflection of an incident electromagnetic wave. 
                         Usually, RAMs are made of a polymeric matrix and an 
                         electromagnetic absorbent filler, such as silicon carbide or 
                         carbon black. Several materials have been investigated as 
                         potential fillers, aiming on the improvement of the reflection 
                         loss (RL) and its frequency broadening. In this paper, we 
                         investigate biochar as a potential filler. Biochar is a 
                         sustainable porous carbon made from biomass waste. We 
                         characterized five different composites, ranging from 1 wt.% to 5 
                         wt.% of biochar in the silicone rubber. Although the RL did not 
                         present a significant result, biochar RAMs can be applied on a 
                         multilayer structure, that is able to attenuate the RL up to -32 
                         dB at 8.2 GHz.",
