Fully stable numerical calculations for finite onedimensional structures: mapping the Transfer Matrix method

摘要

We design a fully stable numerical solution of the Maxwell´s equations with the Transfer Matrix Methodud(TMM) to understand the interaction between an electromagnetic field and a finite, one-dimensional, nonperiodicudstructure. Such an exact solution can be tailored from a conventional solution by choosing anudadequate transformation between its reference systems, which induces a mapping between its associatedudTMMs. The paper demonstrates theoretically the numerical stability of the TMM for the exact solutionudwithin the framework of Maxwell´s equations, but the same formalism can efficiently be applied toudresolve other classical or quantum linear wave-propagation interaction in one, two, and three dimensions.udThis is because the formalism is exclusively built up for an in depth analysis of the TMM´s symmetries
