Whenever two of these waves collide they do not change their shape and speed. Soli tons have a lot of applications in other fields like, fluid, biology and engineering. This dissertation find out the chirped and dipole soliton for nonlinear negative-index ma terials with quadratic-cubic nonlinearity. We will use sub-ODE method [26] to find chirped soliton and ansatz method of Choudhuri and Porsezian [16] to get dipole soli tonenChirped And Dipole Soliton In Nonlinear NegativeAdnan KhalilFA14department of mathematicsThesis
