ABSTRACT. ­ We consider solutions to the time-harmonic Maxwell Equations. For such solutions we
provide a rigorous derivation of the the leading order boundary perturbations resulting from the presence
of a finite number of interior inhomogeneities of small diameter. These formulas generalize those by
Vogelius and Volkov, where only solutions with "transverse electric" and "transverse magnetic" symmetries
were considered. Our formulas may be expected to lead to very effective computational identification
algorithms, aimed at determining specific internal features of an object based on electromagnetic boundary
measurements. 2001 Éditions scientifiques et médicales Elsevier SAS
