2d photonic crystals with cubic structure: asymptotic analysis,into a lossless optically dense host material with the dielectric constant ε > 1. We show that if ε is large enough and the relative distance δ between the air columns is such that εδ ≫ 1 and εδ. ≪ 1, then the corresponding Maxwell operator has a series of gaps in the spectrum. In particular, the ty

On waves in random media in the diffusion-approximation regime,working on waves in random media (F. Bailly, J. Chilian, J.F. Clouet, J.P. Fouque and J. Gamier). These results are based on various generalizations of classical diffusion-approximation results. In the first section we study the spreading of fin acoustic pulse travelling through a randomly layered m
