Specifics of electromagnetic wave propagation through a non-ideal 1D photonic crystal

ABS T R A C T The paper employs mathematical modeling to elucidate the specifics of propagation of electromagnetic excita-tions through a non-ideal one-dimensional photonic crystal. We focus on such key quantities as the refractive index and the width (energy gap) of the lowest forbidden band in the energ y spectrum and study their depen-dence on concentrations of point and layer structural defects (the layers are allowed to va r y in their compositions and thicknesses).

Automated summary

This paper uses mathematical modeling to investigate the propagation characteristics of electromagnetic excitations through a non-ideal one-dimensional photonic crystal. The refractive index and the width of the lowest forbidden band in the energy spectrum are the key quantities of interest, and their dependence on concentrations of point and layer structural defects is studied.
