1 Introduction
The investigations of nonlinear electrical transmission lines and its solitary wave solutions have marvelous applications in communication systems and electronic engineering such as distributing signal of cable television, computer network connection systems, data buses of high speed computer, mobile network systems, connection between transmitters and receivers of radio with their antennas, routing calls in trunk lines between telephone switching centers (Abdoulkary et al., 2013; Arshad et al., 2018; Seadawy, 2017a; Kumar et al., 2018; Aslan, 2016). Moreover, nonlinear electrical transmission lines are used as special medium to carrying the alternate current (AC) of frequency of radio (Abdoulkary et al., 2013). The NLETLs are also used to deliver the better way how to observe the nonlinear excitation be have under nonlinear media and modulate the features of exotic of new systems (Jaradat et al., 2018a,b,c,d; Alquran and Jaradat, 2018; Ali et al., 2019; Alquran et al., 2020; Pelap and Faye, 2005).
For demonstrated of solitary wave solutions for NLEEs describe the wave propagation in nonlinear low-pass electrical transmission lines (Abdoulkary et al., 2013; Arshad et al., 2018; Seadawy, 2017a; Kumar et al., 2018; Aslan, 2016), we consider as:
In Eq. (1), are the real constants and represents to transmission line voltage. The variables represents to distance for propagation and slow time, respectively. The Eq. (1), is derived by applying the Kirchoff’s laws are seen in Abdoulkary et al. (2013), in this current work, which are omitted due to shortness.
In previous years a huge research work have been done on nonlinear low-pass electrical transmission lines. Many researchers have been determined the various types of solutions for NLETLs by using the different techniques including jacobi elliptic technique, kudryashov technique, auxiliary equation technique, -expansion method, extension technique of tanh function, the technique of racatti equation, modification of kudryashov technique, the technique of sine-Gorden and extension of sine-Gorden equation (Abdoulkary et al., 2013; Arshad et al., 2018; Seadawy, 2017a; Kumar et al., 2018; Aslan, 2016). The NLETLs are play important role in the investigation of propagation phenomena of electrical solitons, they are travel in nonlinear media of dispersion in the shape of voltage waves.
The nonlinear wave equations are describing the physical process in many areas of science and engineering include fiber optics, geophysics, chemistry, plasma physics, biology, fluid dynamics, laser physics and so on. The NLETLs are the nonlinear partial differential equations. Now a days it is a deals of huge interest to finding the soliton solutions for NLPDEs by implementing the various techniques. To determine the solutions for NLPDEs play key role and deliver the important information to know the applications and its mechanism. Further, this is very keen to know the concept of specific wave called soliton. John Scott Russel first time introduced a solitary wave in the past few decades (Russell, 1844). When solitary wave is discover after that, now its named solitons. Solitions have potential applications in various kinds of areas including soliton dynamics, fluid dynamic, fiber optics, adiabatic dynamic parameters, phenomena of industrial, biomedical problems, engineering and many various kinds of applied sciences to due to their important stability properties. The nonlinear electrical transmission lines are the example in physics. In previous few decades, a lot of researchers and mathematician introduced a various kinds of methods to determine the solitonic solutions for these NLEEs.
