Negative refraction and left-handed behavior in two-dimensional photonic crystals
S. Foteinopoulou, C. M. Soukoulis
We systematically examine the conditions of obtaining left-handed (LH) behavior in photonic crystals. Detailed studies of the phase and group velocities as well as the phase np and…
Refraction at Media with Negative Refractive Index
S. Foteinopoulou, E. N. Economou, C. M. Soukoulis
We show that an electromagnetic (EM) wave undergoes negative refraction at the interface between a positive and negative refractive index material. Finite difference time domain (F…
Theoretical investigation of one-dimensional cavities in two-dimensional photonic crystals
S. Foteinopoulou, C. M. Soukoulis
We study numerically the features of the resonant peak of one-dimensional (1-D) dielectric cavities in a two-dimensional (2-D) hexagonal lattice. We use both the transfer matrix me…
Localization in Highly Anisotropic Systems
Qiming Li, C. M. Soukoulis, I. Zambetaki +1
The localization behavior of the Anderson model with anisotropic hopping integral t for weakly coupled planes and weakly coupled chains is investigated both numerically with the tr…
Scaling Properties in Highly Anisotropic Systems
Qiming Li, C. M. Soukoulis, S. Katsoprinakis +1
Scaling of the conductances and the finite-size localization lengths is generalized to anisotropic systems and tested in two dimensional systems. Scaling functions of isotropic sys…
Optical Bistability in Colloidal Crystals
E. Lidorikis, Qiming Li, C. M. Soukoulis
We present a one dimensional model for the nonlinear response of a colloidal crystal to intense light illumination along a high symmetry direction. The strong coupling between ligh…
