直接比较了目前文献中出现的两种光栅综合方法。特别是，我们指出了两者之间的相似性，这两种算法都是基于传播的领域通过的结构，同时评估的耦合系数，根据简单的因果关系参数（层剥离算法）。第一个公布的方法（离散层剥离算法）重新制定了一个更简单，更有效的方式，它表明，它的实施可以准确。为了进行数学比较，推导了第二种方法（连续层剥离算法）。在数学上和数值上的方法进行了比较。我们发现，离散层剥离算法是显着更快，可以更稳定，比其连续对应，而连续算法提供了一些优势，在灵活性。
Two methods for grating synthesis which have appeared in the literature recently are compared directly. In particular, we point out the similarity between the two; both algorithms are based on propagation of the fields through the structure with simultaneous evaluation of the coupling coefficient according to simple causality arguments (layer-peeling algorithms). The first published method (the discrete layer-peeling algorithm) is reformulated in a simpler, more efficient way, and it is shown that its implementation can be made exact. For mathematical comparison, a derivation of the second method (the continuous layer-peeling algorithm) is presented. The methods are compared both mathematically and numerically. We find that the discrete layer-peeling algorithm is significantly faster and can be more stable than its continuous counterpart, whereas the continuous algorithm offers some advantages in flexibility.
