The presentation is concerned with the numerical simulation and optimization of optical properties of mono-layered nano-particle films. The optical properties of interest are the transmission through the film and its haze factor. While the transmission can be modeled in a straight forward way based on the time harmonic Maxwell’s equation, for the haze factor a model close to an experimental setup is derived. The numerical solution gets involved due to the resulting size of the computational domain in comparison to the wave length, which renders the direct application of the FEM method infeasible. As a remedy a hybrid method is suggested, in the core of which analytical solutions for the far field are combined with FEM based near filed solutions in a consistent way. Using a series of algebraic reformulations, an off and online model is developed, by which the computational complexity can be reduced by several orders of magnitude. Based on this, structural optimization problems covering geometrical and topological parametrizations are formulated by the help of which the influence of different particle arrangements can be studied.
