Description
The formation and governing of periodically modulated refractive index in medium is a most important problem of solid state physics and material science. First of all it is related to the possibility of developing compact UV or X-ray Free-Electron Lasers (FEL) based on emission of transition radiation (TR).
Currently the following two problems are discussed intensely:
a. A gas-plasma medium with periodically varied ionization density,
b. A special periodical solid-state superlattice-like (SSL) structures composed of layers with different refraction indexes.
