In this work, our main goal is to study a new wave behavior of the nonlinear system associated with ionic wave equations under the influence of the ponderomotive force caused by a nonlinear force experienced by a charged particle in an inhomogeneous oscillating electromagnetic field due to high-frequency field. Another variation in the modified exp-function method has been developed to find progressive wave solutions for the system of sound waveform equations under the pressure of Langmuir wave. The algorithm presented in this work offers new solutions for the complex redundant functions of the nonlinear system in relation to the considered model. Numerical simulations are provided to illustrate the effectiveness of proposed algorithm.
