Modeling of electromagnetic waves propagation in nonlinear optical media using HSCN-TLM method

Modeling of electromagnetic waves propagation in nonlinear optical media using HSCN-TLM method

In this paper, we propose a hybrid symmetrical condensed node TLM approach for the simulation of optical media under femtosecond regime. The formulation is based on the piecewise linear recursive convolution (PLRC) technique, voltage sources and the introduction of the variable admittance concept. Optical solitons with Kerr and Raman nonlinearities are simulated using this novel approach.

Nonlinear Propagation of Electromagnetic Waves in Antiferromagnet

Propagation of nonlinear waves in disordered media

We study the propagation of stationary waves in disordered non-linear media described by the nonlinear Schrödinger equation and show that for given boundary conditions and a given coherent wave incident on the sample, the number of solutions of the equation increases exponentially with sample size. We also discuss the ballistic case, the sensitivity of the solutions to the change of external pa...

Propagation of electromagnetic waves in non- homogeneous media

We consider electromagnetic waves propagating in a periodic medium characterized by two small scales. We perform the corresponding homogenization process, relying on the modelling by Maxwell’s partial differential equations. Key wordsMaxwell’s equations, Homogenization, two-scale convergence, oscillating test functions. (MSC)-2000: 35Q60, 35B27 [email protected] hassan.taha@labo...
