Abstract

In this exploration, we reflect on the wave transmission of three-dimensional (3D) nonlinear electron–positron magnetized plasma, counting both hot as well as cold ion. Treated equation acquiesces to nonlinear-modified KdV-Zakharov–Kuznetsov (mKdV-ZK) dynamical 3D form. The model is integrated by the -model expansion scheme and invented few families of ion acoustic solitonic propagation results in term of Jacobi elliptic functions. Various shock waves, bullet like bright soliton, dark soliton, singular soliton, as well as periodic signal solutions, are formed from the Jacobi elliptic solution for different parametric constraints. Some of the solutions are illustrated graphically and analyzed width and height due to change of exist parameters in the solutions. Figures are provided to explain the wave natures and effects of nonlinear and fractional parameters are presented in the same two-dimensional (2D) plots.

1. Introduction

The exploration on nonlinear evolution models (NEMs) has a verity of significant functioning in science and engineering applications. It is proverbial that NEMs are frequently used to illustrate various imperative happenings and progressions in abundant technical scientific fields, resembling epidemiology, stratified internal waves, meteorology, solid-state physics, plasma physics, ocean engineering, ion acoustic, fiber optics, and more others [1–4]. Therefore, the study of accurate exact solutions to realize internal properties of NEMs demonstrates a crucial task for understanding of the majority nonlinear substantial happenings or acquiring novel occurrences. More scientists expended efforts to release inventive proficient procedures designed for explanation of interior properties of NEMs amid with constant coefficients has been established such as a distinct arithmetic structure [5], IRM-CG technique [6], transformed rational function method [7], fractional residual technique [8], new multistage procedure [9], new analytical method [10], extended tanh scheme [11], Hirota-bilinear scheme [12–14], multi exp-expansion technique [15, 16], the Kudryashov and the extended sine-Gordon schemes [17], variable separation method [18], MSE method [19], the nonlinear capacity [20], Jacobi elliptic function [21], the pitchfork bifurcation [22], ansatz method [23], higher order rogue wave [24], fractional natural decomposition method [25], generalized exponential rational function scheme [26], numerical and three analytic schemes [27], -expansion scheme [28], the -model method [29, 30], and so on. All of the above techniques provide sinusoidal and hyperbolic results. To acquire the solutions, which cover all sinusoidal and hyperbolic solution even express more complex phenomena, Jacobi elliptic function [21] and the -model expansion [29, 30] schemes are exceptional. These two methods are highly important as it gives Jacobi elliptic function solutions. The sinusoidal and hyperbolic solutions are exceptional suitcases of the Jacobi elliptic function. Owing to this fact, we sport light on the (3 + 1)-D nonlinear mKdV-ZK model in bellow [31–34].where is the nonlinear coefficient and is the electric field potential. The model is utilized in controlling properties of dimly nonlinear ion-acoustic patterns within electron–positron magnetized plasma, counting the hot–cold mechanism of each type [30–33]. The model also arises in diverse branches of physical areas like plasma physics, optical system, fluid flows, and quantum mechanics. Due to importance of the model, huge effort has been paid on the mKdV-ZK model: Xu [31] applied an elliptic equation technique and derived only five elliptic solution; Kumer and Verma [32] found dynamics of invariant solutions via extended -expansion method of the model; Lu et al. [33] constructed analytical wave solutions via Lie symmetry analysis scheme; Seadawy [34] analyzed the stability and derived stable solutions of the mKdV-ZK model, etc. Dynamical scientists were considered more plasma models [35–38] to analyze plasma fluid, and represented the systems of equation into KP-Burgers [35], ZK and eZK [36], and ZK and mZK [37, 38], with proper explanations of each plasma parameters. The Jacobi elliptic function solution of mKdV-ZK model in fractional differential form is still unexplored in the literature. Owing to this fact, this research is willing to increases the complex nonlinear dynamics in term of Jacobi elliptic function of the model as well.

2. Sketch of the -Model Expansion Method

An analytical technique of deriving Jacobi elliptic solutions is a recent -model expansion scheme, which was first invented via Zayed et al. [29]. Due to its effectiveness and novel finding efficient, we aim to execute it on a nonlinear evolution equation (NLEE) whose key steps are given as follows: Step 1: Let us reflect on the following general NLEE in the form given as follows:where is an expression of , as well as various order partial derivatives, involving nonlinearity. Step 2: Assembling wave adaptation relation is given as follows:where signify traveling variable, wave number, and phase velocity, respectively. Equation (3) is reduced to Equation (2) into the nonlinear ODE as shown below:in which derivatives due to are signified with prime. Step 3: Assume a trial solution of Equation (4) subsists and can be written in a series as follows:where is to be evaluated. Using balance law, can be achieved [26–28], and suits the assisting nonlinear ordinary differential equation (NLODE):where is in variables that can be revealed afterward. Step 4: An answer to Equation (6) is in the following form:under setting and are elliptic function that comes from:where is unspecified constants and particular values of these will be evaluated, while and come from:with the constraint condition: Step 5: According to Zayed et al. [29], it is recognized that the Jacobi elliptic function solution of Equation (8) exhibits for , otherwise it will be sinusoidal or hyperbolic function solutions for Determination of solutions of Equation (2) will be completed taking advantages of Equations (7) and (8) into Equation (5).

3. Implementation of the -Model Expansion Scheme

Let us reflect on the well-known nonlinear evolution model mKdV-ZK EEquation (1) in [31–34], and we can convert it to an ODE with the wave mapping relation given as follows:where represents wave velocity and are wave numbers in the directions, respectively.

5. Conclusions

This paper had achieved ion-acoustic soliton solutions to mKdV-ZK model in homogeneous magnetized plasma media via the -model expansion scheme. We successfully utilized and invented novel families of ion-acoustic solitons propagation due to Jacobi elliptic forms. Various shock waves, bullet type bright, dark, bright-dark solitons, as well as periodic wave solutions are formed starting the Jacobi elliptic results on different parametric constraints. Some obtained results are numerically illustrated in Figures 1–4 and analyzed the effect of nonlinearity on the change of height and weight of the wave form in 2D, 3D plots. The activities and the transmission of such solutions are discussed in a rating index waveguide for selecting suitable parameters. To best our knowledge, the achieved dynamical natures, in contrast with other’s results in literature, are innovative in dissimilar structures. Such critical behaviors can be crucial to recognize attribute of the mKdV-ZK model those are used to explain various phenomena in nonlinear sciences.
