2. Calculation method

2.1 Problem definition

We place ourselves in a harmonic or monochromatic regime with a time dependence in exp (– jωt ). Media are assumed to be linear, homogeneous, isotropic and non-magnetic (μ = μ ₀ ). We also work in the absence of charges and currents, without excluding the case of metals (photo-induced currents). The component is a multilayer planar system (figure 2 ) invariant along Oy. This component is illuminated from a source located at infinity in a transparent superstrate of refractive index n...
