Low-frequency electromagnetic scattering 

Authors:       H. Ammari and J.-C. Nedelec 

Abstract: The main result of this paper is to reduce the calculation 
of higher-order terms in the asymptotic expansions of the electric 
and magnetic fields at low frequencies  to the solutions of certain 
canonical  problems. We also  provide a new and simple variational
proof of the convergence of the electric and magnetic fields solutions of
the scattering problem for the Maxwell equations as the frequency 
goes to zero. Besides its theoretical interest, our analysis is motivated
by its application to the numerical computation of the higher-order terms.
