"The processing of radiation absorbing materials hu00ecbridos using webs polymeric, hives, foams and coatings added with ferrite of barium (BA), lead (PB), cobalt (CO), chromium (CR),Scandium (SC), manganese (MN), nu00ecquel (Ni), titanium (TI) and zinc (Zn) and / or partu00ecculas of black smoke and / or graphite, in the range of 1 GHz to 40 GHz.Patent of invention of a process of manufacture of absorbing materials of radiation hybrids (marh) by the combination of absorbing type webs polymeric, hives,Foams and paint added with ferrite of barium, lead, cobalt, chromium, manganese, nickel and scandium.Titanium and zinc and / or particles of carbon black and / or graphite and / or metallic filaments ferrocarbonila, for applications such as electromagnetic shielding in the sectors of telecommunications, radars,Aerospace and the like.Obtaining the marh begins by processing isolated from different types of absorbers, such as blankets, foams,Hives or red duly impregnated with additives absorbing radiation.The appropriate combination of absorbers isolates depends on the range of frequ00b3u00eancia use of marh and can be guided by the use of simulators, computer aided design (CAD) or from the VALaw of magnetic permeability and permittivity of the absorbers.The efficiency of the attenuation of the incident radiation is measured using the technique of the NRL (Naval Research Laboratory) or by the method of absorption.
