Abstract:
 This paper  deals with the low-frequency  scattering problem by a conducting
object  in a chiral medium. With boundary integral equation methods, we obtain
the limit of the scattered field, solution  of the Drude-Born-Fedorov equations
as frequency tends to zero. Making use of a  Hodge decomposition of the
tangent
fields shows  that the asymptotics strongly  depend on the topological
properties
 of the domains under consideration. The asymptotic expansion's  dependence
on the
chirality parameter is completely shown.
