Web11 Apr 2024 · Can it be a sum of an infinite series? If you want to treat it like that, then yes. Fortunately, this will generically be some form of a geometric series, $$ \sum_{n=0}^\infty r^n = \frac{1}{1-r}, \tag 1 $$ with a factor $ r \leq 1$ (since the reflectivities are all bounded by unity), so they can be summed exactly. This is, of course, not a coincidence, and you … Web6 Jan 2012 · If the film is thin (~100 nm) no fringes appear in the VIS-UV region. The Manifacier approach cannot be applied and one has to fit the whole curve taking into account the lambda dependence of n and k.
