Abstract : In this thesis, we provided an overview to plasma and types of waves. The korteweg-de Vries (KdV) equation and modified KdV (mKdV) equation are derived using the reductive perturbation technique for fluid equations. The damped Kawahara equation is solved using the ansatz / hypothesis method. Then, the nonplanar (spherical and cylindrical) modified Kawahara equation (nmKE) is solved using the ansatz approach. Two general formulas for the semi-analytical symmetric approximations are derived using the recommended methodology. Using the obtained approximations, the nonplanar modified Kawahara (nmK) symmetric soliatry waves (SWs) and cnoidal waves (CWs) are obtained. The fluid equations to the electronegative plasmas are reduced to the nmKE as a practical application to the obtained solution. Using the obtained solutions, the characteristic features of both cylindrical and spherical mK SWs and CWs are studied. All obtained solutions are compared with each other and the maximum residual errors for these approximations are estimated. Numerous researchers that are interested in studying the complicated nonlinear phenomena in plasma physics can use the obtained approximations to interpret their experimental and observational findings.
