WebAbstract A generalized matrix method to treat multilayer systems with mixed coherent and incoherent optical behavior is presented. The method is based on the calculation of the light energy flux inside the multilayer, whose internal light absorption is straightforwardly derived. WebA coherent boundary is one for which atomic positions on either side of the boundary are correlated. This is illustrated for a coherent precipitate (yellow) in the top diagram. The lower diagram shows a similar precipitate, but with an incoherent boundary. Atoms in the matrix and the lattice are no longer in register across the interface. If ... phillies wife
