             abstract = "Radar absorbing materials (RAMs) are composites made with a 
                         polymeric matrix and an electromagnetic absorbing filler, such as 
                         carbon black (CB), silicon carbide (SiC) or manganese zinc ferrite 
                         (MnZn). To enhance their performances to attenuate an incident 
                         wave through reflection loss (RL), RAMs can be produced in 
                         multilayer structures. Usually, the RL analysis is done 
                         theoretically and experimentally validated with free space 
                         analysis. Here, it was demonstrated that multilayer structure can 
                         be designed and easily validated using rectangular waveguide, 
                         using a simpler setup and small samples. Three composites were 
                         produced using 2 wt% of CB (CB2), 40 wt% of SiC (SiC40) and 60 wt% 
                         of MnZn (MnZn60). They were characterized over the Ku-band and 
                         used to validate the multilayer structures, that were prepared by 
                         simply stacking each material inside the waveguide sample holder. 
                         One of the best results was obtained with structure SiC40+CB2 with 
                         5.85 mm thickness, that presented a calculated RL of-21 dB at 17.8 
                         GHz and a measured RL of-36 dB at the same frequency. In 
                         conclusion, using rectangular waveguide has been proven to be an 
                         easy, cheap, precise and fast approach to validate multilayer 
                         structures designs. © 2021, Journal of Aerospace Technology and
