Nous considérons des solutions des équations de Maxwell dans R3 en présence d'un nombre fini d'inhomogénéités de petits diamètres. Pour de telles solutions, nous obtenons des formules asymptotiques rigoureuses. Puis, nous décrivons le comportement de l'énergie électromagnétique.

We consider solutions to the time-harmonic Maxwell problem in R3. For such solution we propose a rigorous derivation of the asymptotic expansions in the interesting practical situation when a finite number of inhomogeneities of small diameter are embedded in the entire space. Then, we describe the behavior of the electromagnetic energy caused by the presence of these inhomogeneities.
