The optical response of two‐phase composite materials (cermet topography with coinage metals) at high filling factors under a wide range of particles sizes, frequencies, and experimental conditions is calculated using a model that combines multipolar interactions and particle size effects. The validity of the model is established for a real system of a silver colloid and the simulations are discussed in terms of the microscopic structural parameters and the interaction between the particles. The limitations of the Maxwell–Garnett model are explored and the transition between a dense system which primarily reflects light and a dilute composite which mostly transmits light is followed with the same model.
