Photonic Gap Materials

J.B. Pendry


The concept of a photonic material is explained in terms of Bragg diffraction. Analogies are also made with electrons in semiconductors, Possible routes to manufacture of these structures are explored as some naturally occurring micro-periodic structures. The article concludes by giving some background to computational modelling of these materials.
