Conductance of photons in disordered photonic crystals [PDF]
Physical Review E, 2005 The conductance of photons in two-dimensional disordered photonic crystals is calculated using an exact multipole-plane wave method that includes all multiple scattering processes. Conductance fluctuations, the universal nature of which has been established for electrons in the diffusive regime, are studied for photons, in both principal polarizations ...

Function photonic crystals [PDF]
Physica E: Low-dimensional Systems and Nanostructures, 2011 In the paper, we present a new kind of function photonic crystals, which refractive index is a function of space position. Unlike conventional PCs, which structure grow from two materials, A and B, with different dielectric constants $ε_{A}$ and $ε_{B}$.
