Analytical solutions to the pulsed Klein–Gordon equation using Modified Variational Iteration Method (MVIM) and Boubaker Polynomials Expansion Scheme (BPES)

In this study, we propose an analytical solution to the Klein–Gordon equation in a pulsed stationary regime. The performed protocols are based on the modified variational iteration method MVIM and Boubaker polynomials expansion scheme BPES.The results are presented, and compared with some solutions proposed later in order to confirm the good accuracy of the protocols used.
