    These two solutions are plotted in Figure 4.20 and it can be clearly seen that the characteristic of the coating is a single minimum with a narrower bandwidth than the single layer and that the broader of the two possible solutions is associated with the thinner high-index layer. The coating is also an effective one for other values of substrate index. The higher the index of the substrate, the thinner the high-index layer must be and the broader is the characteristic of the coating.

    We can follow Catalan [2] and plot curves showing how the values of δ1 and δ2 vary with the index of the layer next to the substrate. Such curves are shown in Figure 4.21 and from them several points of interest emerge.

    First, as already predicted by the Schuster plot, there is a region in which no
