EXERCISE 7.1-1: Quarter-Wave Film as an Antireflection Coating. Specially designed thin dielectric films are often used to reduce or eliminate reflection at the boundary between two media of different refractive indices. Consider a thin film of refractive index and thickness d sandwiched between media of refractive indices n and na. Derive an expression for the B element of the M matrix for this multilayer medium. Show that light incident from medium 1 has zero reflectance if d = 1/4 and n = n^3
