The high proliferation of electronic instruments especially in
the telecommunication area causes electromagnetic interferences
(EMI) and disturbs the effective performance of electronic or
electrical circuits in military and civil uses [1,2]. To assume the
safety operation of electronic devices, standard rules are imposed
to the designers of electronic equipments to protect those against
the aggression of electromagnetic waves. Then, the designers
have to conceive enclosures to limit the coupling between the
electromagnetic field and the electronic circuits. In regard to the
application, these enclosures have to reflect or absorb the electromagnetic
waves. In stealth weapon defense system, advanced
composite materials are used as electromagnetic absorbing materials
(EMAMs) to attenuate the electromagnetic beam and reduce
the radar cross section (RCS) [3,4]. Thus, several needs to develop
thinner and lighter electromagnetic wave absorbers with wider
