             abstract = "Due to their remarkable mechanical and electrical properties, 
                         carbon nanotubes (CNTs) and their composites are great candidates 
                         for materials with improved electromagnetic and electrical 
                         properties. Above all, when used in conjunction with magnetic 
                         particles, for example, carbonyl iron and ferrites, the energy 
                         losses can be improved, minimizing the microwave reflections. This 
                         work studies the influence of magnetic particles (carbonyl iron 
                         and magnetite ferrite) on the electromagnetic behavior of carbon 
                         nanotube buckypaper (BP) reinforced epoxy composites over the 
                         frequency range 8.2 12.4 GHz. Firstly, the carbonyl iron and 
                         magnetite ferrite were dispersed in the epoxy resin, and their 
                         electromagnetic properties were analyzed. Epoxy/carbonyl iron 
                         composites showed reduced reflection losses at 10 GHz (SER = 
                         1.521.99 dB) and improved absorption results (SEA = 0.475.78 dB). 
                         Epoxy/magnetite samples showed higher SER and SEA than carbonyl 
                         iron samples, with values ranging around 1.723.93 dB and 0.437.21 
                         dB at 10 GHz, respectively. The addition of carbon nanotube 
                         buckypaper in the carbonyl iron composites resulted in SEA values 
                         up to 19.68 dB at 10 GHz. Besides, the BP/magnetite composites 
                         showed SEA of 18.58 dB at the same frequency. The total shielding 
                         efficiency (SET) was reached with 40 % wt. of magnetite (SET = 
                         21.60 dB, at 10 GHz) and 70 % wt. of carbonyl iron (SET = 23.43 
                         dB, at 10 GHz). Despite the variation in the magnetic filler 
                         concentration, all ternary hybrid composites showed increased 
                         absorption properties. This behavior is attributed to the 
                         synergistic effect between both magnetic particles and carbon 
                         nanotube buckypaper on the shielding properties of the studied 
                         composites.",
