Abstract:
The theory presented by Gerardyand Ausloos for the calculation of the linear optical response of aggregates of spherical particles is analytically continued for absorbing
embedding media. The method is based on the calculation of the extinction rate by a single particle embedded in an absorbing
matrix. Explicit expressions for the extinction and scattering cross-sections are given. The method is applied to calculate
the energy losses in several organic matrices with embedded silver clusters. Comparison with experimental data shows a very
good agreement.
