A closed-form expression approximating the Mie solution for the real-in-line transmission of ceramics with spherical inclusions or pores

Popis výsledku v původním jazyce

A new closed-form expression is presented for estimating the real-in-line transmission of ceramics consisting of non-absorbing phases in dependence of the inclusion or pore size. The classic approximations to the exact Mie solution of the scattering problem for spheres are recalled (Rayleigh, Fraunhofer, Rayleigh-Gans-Debye / RGD, van de Hulst), and it is recalled that the large-size variant of the RGD approximation is the basis of the Apetz-van-Bruggen approach. All approximations and our closed-form expression are compared mutually and vis-a-vis the exact Mie solution. A parametric study is performed for monochromatic light in the visible range (600 nm) for two model systems corresponding to composites of yttrium aluminum garnet (YAG, refractive index 1.832) with spherical alumina inclusions (refractive index 1.767), and to porous YAG ceramics with spherical pores (refractive index 1). It is shown that for the YAG-alumina composites to achieve maximum transmission with inclusion volu
