Coherent Structures in Nonlocal Dispersive Active-Dissipative Systems

We analyze coherent structures in nonlocal dispersive active-dissipative nonlinear systems, using as a prototype the Kuramoto–Sivashinsky (KS) equation with an additional nonlocal term that contains stabilizing/destabilizing and dispersive parts. As for the local generalized Kuramoto–Sivashinsky (gKS) equation (see, e.g., [T. Kawahara and S. Toh, Phys. Fluids, 31 (1988), pp. 2103–2111]), we sho...

Magnetic field induced transient periodic dissipative structures in nematics

The lJnearized version of nonstochastic cont~nuum theory is used wJth the ngid anchonng hypothesis to study the occurrence of transient penodic dissipative structures (DS) induced m a nematic sample by a magnetic field H of supercritical strength applied m a

Finite-Difference Time-Domain Simulation of Light Propagation in 2D Periodic and Quasi-Periodic Photonic Structures

Ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. Therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. We...

Dissipative Solitary Waves in Periodic Granular Crystals

We provide a quantitative characterization of dissipative effects in one-dimensional granular crystals. We use the propagation of highly nonlinear solitary waves as a diagnostic tool and develop optimization schemes that allow one to compute the relevant exponents and prefactors of the dis-sipative terms in the equations of motion. We thereby propose a quantitatively-accurate extension of the H...
