The nonlinear Schrödinger equation has wide range of applications in physics with spatial
scales that vary from microns to kilometres. Consequently, its solutions are also universal …

We present one-and two-breather solutions of the fourth-order nonlinear Schrödinger
equation. With several parameters to play with, the solution may take a variety of forms. We …

Considering the theory of electromagnetic waves from the Maxwell's equations, we
introduce a (3+ 1)-dimensionsal cubic-quintic complex Ginzburg-Landau equation …

The topics here deal with some current progress in electromagnetic wave propagation in a
family of substances known as metamaterials. To begin with, it is discussed how a pulse can …

We present the second order rogue wave solutions of the Sasa–Satsuma evolution equation
that have significantly more complicated structure than in the case of the nonlinear …

We examine the cubic-quintic-Raman influences on the system when the second-order
dispersion and the cubic-quintic-nonlinearities act in a double-negative material. This …

The goal of this investigation is based on electromagnetic wave behavior which is modeled
by a nonlinear Schrödinger equation in a nonlinear metamaterial optical system. Two …

We demonstrate at the first time that the left-handed transmission line with varactor diodes
can support higher-order effects. So, we establish at the first time, a nonlinear Schrödinger …

In this work, we present a particular nonlinear transmission line called chameleon nonlinear
transmission line. In fact, the chameleon's behavior is related to the fact that without …

In this work, we present a new Ansatz function called” type I Ansatz function” with seven
collective coordinates compared to the conventional Gaussian Ansatz function with six …
