    same as refractive index. Two possible arrangements are shown in Figure 4.7, which can be obtained simply by drawing the circle corresponding to index n1, passing through the point n0, and the circle corresponding to index n2 passing through the point nm. Provided these circles intersect, then an anti- reflection coating using them is possible. The two sets of thicknesses corre- spond to the two points of intersection.

    This is a very important coating with wider implications than just the blooming of a high-index substrate and so it is worth examining in greater detail. We use the matrix method and follow an analysis by Catalan [2], changing the notation to agree with the system used here.
