Mode Repulsion and Mode Coupling in Random Lasers
H. Cao, Xunya Jiang, Y. Ling +2
We studied experimentally and theoretically the interaction of lasing modes in random media. In a homogeneously broadened gain medium, cross gain saturation leads to spatial repuls…
Transmission Losses in Left-handed Materials
P. markos, I. Rousochatzakis, C. M. Soukoulis
We numerically analyze the origin of the transmission losses in left-handed structures. Our data confirms that left handed structures can have very good transmission properties, in…
Conductance fluctuations and boundary conditions
Marc Ruehlaender, Peter Markos, C. M. Soukoulis
The conductance fluctuations for various types for two-- and three--dimensional disordered systems with hard wall and periodic boundary conditions are studied, all the way from the…
Symmetry, dimension and the distribution of the conductance at the mobility edge
Marc Ruhlander, Peter Markos, C. M. Soukoulis
The probability distribution of the conductance at the mobility edge, , in different universality classes and dimensions is investigated numerically for a variety of random…
The probability distribution of the conductance in anisotropic systems
Marc Ruehlaender, Peter Markos, C. M. Soukoulis
We investigate the probability distribution of the conductance in anisotropic two-dimensional systems. The scaling procedure applicable to mapping the conductance distri…
Localized Random Lasing Modes and a New Path for Observing Localization
Xunya Jiang, C. M. Soukoulis
We demonstrate that a knowledge of the density-of-states and the eigenstates of a random system without gain, in conjunction with the frequency profile of the gain, can accurately…
The probability distribution of the conductance at the mobility edge
Marc Ruhlander, C. M. Soukoulis
The probability distribution of the conductance p(g) of disordered 2d and 3d systems is calculated by transfer matrix techniques. As expected, p(g) is Gaussian for extended states…
Metal-insulator transitions in anisotropic 2d systems
Marc Ruhlander, C. M. Soukoulis
Several phenomena related to the critical behaviour of non-interacting electrons in a disordered 2d tight-binding system with a magnetic field are studied. Localization lengths, cr…
Time Dependent Theory for Random Lasers
Xunya Jiang, C. M. Soukoulis
A model to simulate the phenomenon of random lasing is presented. It couples Maxwell's equations with the rate equations of electronic population in a disordered system. Finite dif…
Pulse driven switching in one-dimensional nonlinear photonic band gap materials: a numerical study
E. Lidorikis, C. M. Soukoulis
We examine numerically the time-dependent properties of nonlinear bistable multilayer structures for constant wave illumination. We find that our system exhibits both steady-state…
Gap deformation and classical wave localization in disordered two-dimensional photonic band gap materials
E. Lidorikis, M. M. Sigalas, C. M. Soukoulis +1
By using two ab initio numerical methods we study the effects that disorder has on the spectral gaps and on wave localization in two-dimensional photonic band gap materials. We fin…
Symmetry between absorption and amplification in disordered media
Xunya Jiang, Qiming Li, C. M. Soukoulis
We address the issue of whether amplification, like absorption, suppresses wave transmission at large gain, as has been claimed in previous studies of wave propagation in active ra…
Transmission and reflection studies of periodic and random systems with gain
Xunya Jiang, C. M. Soukoulis
The transmission (T) and reflection (R) coefficients are studied in periodic systems and random systems with gain. For both the periodic electronic tight-binding model and the peri…
What is the right form of the probability distribution of the conductance at the mobility edge?
C. M. Soukoulis, Xiaosha Wang, Qiming Li +1
The probability distribution of the conductance Pc(g) at the Anderson critical point is calculated. It is find that Pc(g) has a dip at small g in agreement with epsilon expansion r…
Comment on "Energy Velocity of Diffusion Waves in Strongly Scattering Media"
C. M. Soukoulis, K. Busch, M. Kafesaki +1
A comment on the recently published article (PRL 79, 3166 (1997)) is given. The issue is if there is a unique self-consistent way in determining the effective medium in a random me…
Tight-binding parameterization for photonic band gap materials
E. Lidorikis, M. M. Sigalas, C. M. Soukoulis +1
The ideas of the linear combination of atomic orbitals (LCAO) method, well known from the study of electrons, is extended to the classical wave case. The Mie resonances of the isol…

Xiashoa Wang, Qiming Li, C. M. Soukoulis
We investigate the scaling properties of zero temperature conductances at integer quantum Hall plateau transitions in the lowest Landau band of a two-dimensional tight-binding mode…
