Description
Summary:[Display omitted] ► Model of electromagnetic properties of OLEDs based on plane wave representation. ► Model revised on the basis of the S-matrix propagation algorithm. ► Exact and simple analytic formulae. ► Model provides calculating power emission and losses in all parts of a structure. ► Consistency of the model is shown by comparison with experimental results. A new approach for the simulation of OLEDs based on a plane wave field expansion is proposed. Exact general formulae are given that allow for the calculation of their optical characteristics including losses in all layers in an arbitrary OLED structure. The S-matrix approach is used which ensures numerical stability of the algorithm. A simple way is proposed to take into consideration non-coherent reflections in a thick substrate. The validity of the model is demonstrated by comparing with experimental data.
