A simple geometric-optics formula to the absorption cross section of a two-layer sphere is derived and analyzed. The case of particles with nonabsorbing shells is studied separately. The results of calculations performed using the exact theory of scattering for two-layered particles were used to determine the limits of applicability of the approximation.
