Why the Refractive Index Couldn't Be Negative

It had been shown that for left-handed metamaterials and generally for negative refraction media the refraction index could not be introduced uniformly and could not be considered as real, especially as negative. This index for above referred media is not expedient.

Integral Equations for Photonic Crystal Fibers

The integral and integrodifferential equations for photonic crystal waveguides (fibers) have been obtained both for finite and infinite dimensions of quasiperiodic dielectric coverings. Previously the equations for two-dimensional periodic photonic crystals with magnetodielectric and metallic periodic inclusions have been considered. The corresponding numerical results are presented.
