  • Solitons solutions of nonlinear Schr?dinger equation in the left-handed metamaterials by three different technique

    摘要： This paper, derives the exact traveling-wave solution and soliton solutions of nonlinear Schr?dinger equation (NLSE) with higher-order nonlinear terms of Left-handed metamaterials (LHMs), the authors apply three different methods, namely: csch function method, the exp(?φ(ξ))-Expansion method and the simplest equation method. The results obtained are Dark, Bright solitons and other solutions, which are well known in optics metamaterials and LHMs.

  • OPTICAL SOLITONS WITH DIFFERENTIAL GROUP DELAY FOR COUPLED KUNDU–ECKHAUS EQUATION USING EXTENDED SIMPLEST EQUATION APPROACH

    摘要： The extended simplest equation approach is implemented to secure soliton solutions, having differential group delay, for Kundu–Eckhaus equation in presence of four–wave mixing terms. The algorithm also lists additional solutions that emerge from the scheme as a byproduct.
