To apply the layer iteration method of low-energy electron diffraction to the diffraction of UV and visible light, the transmission and reflection coefficients of the electromagnetic waves are derived for a two-dimensional periodic array of dielectric spheres with an isotropic dielectric constant. The concepts of phase shifts and t matrix are introduced for light scattering. The theory is a direct extension of Kambe's LEED theory (1968). Also, the secular equation obtained for the bandstructures of photons is a generalisation of the Korringa-Kohn-Rostoker formalism of electronic band calculation.
