We present a novel way to account for partially coherent interference in multilayer systems via the transfer-matrix method. The novel feature is that there is no need to use modified Fresnel coefficients or the square of their amplitudes to work in the incoherent limit. The transition from coherent to incoherent interference is achieved by introducing a random phase of increasing intensity in the propagating media. This random phase can simulate the effect of defects or impurities. This method provides a general way of dealing with optical multilayer systems, in which coherent and incoherent interference are treated on equal footing.

    • "We have used Θ¼0.1 which means that variations up to 10% in the thicknesses are considered for those layers of the structure beyond the 148th layer. Our approach to incorporate the effect of partially noncoherent propagation of light is different from that followed by Santbergen et al. [19] and Troparevsky et al. [20] who introduce incoherent propagation by adding a random number to δ i . Fig. 5 shows the results of adding a background contribution to R ð1Þ c due to non-coherent reflection of the endocuticle layers: "

    ABSTRACT: Under normal incidence of non-polarized light, reflection spectra from the cuticle of golden-like C. aurigans scarabs shows a broad reflection band displayed from 525 to 950 nm, with a spectral ripple structure that consists of a uniform sequence of peaks superimposed on the main reflection band. Cross sectional Scanning Electron Microscope (SEM) images of the cuticle initially suggest the presence of a multilayered structure. A radiative transfer matrix formalism is first applied to describe as much as possible the main features of coherent reflection spectra, by assuming optically homogenous layers distributed through the exocuticle, with chitin as the major constituent material. Additional non-coherent multiple reflections due to layers in the endocuticle is also evaluated from this approach. The presence of a pigmented micron sized structure beneath the procuticle requires the evaluation of a diffuse light contribution to the reflection. This was carried out from a four-flux radiative transfer model. Optical anisotropy is introduced by interpreting the SEM images in terms of a twisted Bouligand-type structure, and reflection spectra are evaluated from an implementation of the so-called 4×4 Berreman's formalism. We have been able to approach the main features characterizing the reflection spectra of C. aurigans' elytra following this progressive way.

    • "To find coherent transmittance and reflectance of the multilayer we use the transfer matrix method (TMM) [26] [27] [28] which takes into account multiple reflections between interfaces. We consider the monolayers as interfaces characterized by amplitude coherent transmission and reflection coefficients, and the spaces between the monolayer planes (the planes where the particle centers are located) as layers with thickness h and refractive index n env [12,40–42].

    ABSTRACT: A method to retrieve characteristics of ordered particulate structures, such as photonic crystals, is proposed. It is based on the solution of the inverse problem using data on the photonic band gap (PBG). The quasicrystalline approximation (QCA) of the theory of multiple scattering of waves and the transfer matrix method (TMM) are used. Retrieval of the refractive index of particles is demonstrated. Refractive indices of the artificial opal particles are estimated using the published experimental data.

    • "It takes only a few minutes on a personal computer. It is an important improvement in terms of computational time, in comparison with other computational methods [15] [16] [17] [18] [19] [20] [21] [22] [23]. In these methods, the first step is performed several times for various incident waves, and the final result relies on a global numerical statistical analysis. "

    ABSTRACT: Because of the temporal incoherence of sunlight, solar cells efficiency should depend on the degree of coherence of the incident light. However, numerical computation methods, which are used to optimize these devices, fundamentally consider fully coherent light. Hereafter, we show that the incoherent efficiency of solar cells can be easily analytically calculated. The incoherent efficiency is simply derived from the coherent one thanks to a convolution product with a function characterizing the incoherent light. Our approach is neither heuristic nor empiric but is deduced from first-principle, i.e. Maxwell's equations. Usually, in order to reproduce the incoherent behavior, statistical methods requiring a high number of numerical simulations are used. With our method, such approaches are not required. Our results are compared with those from previous works and good agreement is found.
