Abstract
The light propagation properties of a slab that consists of periodic multilayers of two materials with different refractive indices are studied. Optical transmittance properties against various wavelengths are calculated by using an orthodox method of a characteristic matrix of a stratified medium. By using a finite-difference-time-domain method, light propagation properties of the slab, especially in the near-field, are simulated. Generally speaking, the presence of the slab promotes light propagation. Extraordinary light propagation, including splitting into two branches, can be observed repeatedly, and in some specific cases a focusing effect can be realized. Realization of negative refraction is checked.
