The extinction coefficient for a low-density dispersion of small stratified spheres as well as for that of their binary aggregates has been calculated. We discuss the results for 50 A spheres with a core of MgO and a coating of A1, a case in which a dramatic shift of the resonance peaks as a function of the thickness could produce selective extinction in a wide range of frequency, although this effect could be strongly weakened if a considerable percentage of spheres aggregate.
