Abstract : An asymptotic expression of the scattered electromagnetic far-field due to a small spherical dielectric inclusion illuminated by an impulsive vector source nearby is proposed first. Then, a time-reversal technique enabling to locate the position of this inclusion is developed and its performances are illustrated from numerical simulations.
