@article{Gevorkian2019StraighteningOL, title={Straightening of light in a one dimensional dilute photonic crystal}, author={Zhyrair Gevorkian and Vladimir Gasparian and Emilio Cuevas}, journal={Scientific Reports}, year={2019}, volume={9} }
Light transport in a dilute photonic crystal is considered. The analytical expression for the transmission coefficient is derived. Straightening of light under certain conditions in a one-dimensional photonic crystal is predicted. Such behavior is caused by the formation of a localized state in transversal motion. The main contribution to the central diffracted wave transmission coefficient is due to states, that either close to the conductance band’s bottom or deeply localized in the forbidden…
