... band structure of the crystal, meaning that electrons are forbidden to propagate with certain energies in certain ... band gap. For example, a semiconduc- tor has a complete band gap between the valence and conduction energy bands. The ...
... band gap in the plane of periodicity. By analyzing field patterns of some electromagnetic modes in different crystals, we gain insight into the nature of band gaps in complex periodic media. We will see that defects in such two ...
... band number. If the spectrum is discrete for a given k, we can use integers for n, but sometimes the band number is ... structure (also called a band diagram or dispersion relation) is shown in figure 3 and is considered in more detail ...
... band structure with L > ck is called the light cone. The modes in the light cone are solutions of Snell's law (less than the critical angle). In addition to the light cone, the glass plate introduces new electromagnetic solutions that ...
... band number . The information contained in these functions is called the band structure of the photonic crystal . Studying the band structure of a crystal supplies us with most of the information we need to predict its optical ...
