After a brief overview of the concept of electromagnetic chirality, th
is paper deals with a numerical simulation of isotropic composites wit
h metallic chiral inclusions: computations of permittivity, permeabili
ty and chirality parameter as functions of frequency are presented. Th
e theoretical results are, step by step, compared with measurements of
chiral composites at microwave frequencies. The application of such m
edia in Radar Cross-Section (RCS) management and control is discussed.
The introduction of chiral inclusions seems to make impedance matchin
g possible and may lead to attractive shields with lower reflectivity
and larger band-width. However the optimization of material characteri
stics necessary to get a specific absorber remains a difficult task.
