abstract = "Composite materials based on Manganese and Zinc Ferrite (FeMnZn),
Carbon Xerogel (XC) and Carbon Xerogel with Graphene (XCG) were
produced to characterize the influence of XCG absorbing
electromagnetic material. The properties of electrical
permittivity and magnetic permeability were calculated to study
the electromagnetic behavior of the composites. The tangent of
electric and magnetic loss was analyzed to evaluate the capacitive
or dissipative system in each composition. The electromagnetic
absorption potential was measured in the Reflection Loss method on
X-Band range (8.2-12.4 GHz), due to its application in the
Aerospace sector. The results showed a potential of -31dB
(\≈99.92% absorption) at 12.4 GHz for a thickness of 1.9
mm. The XCG presented great applicability as a reinforcement to
increase the electromagnetic absorption potential of composites
based on FeMnZn.",
