    (Library Information Services, COMSATS University, Lahore Campus, 2016) Adnan Khalil,; FA14-BSM-012; Dr. Syed Tahir Raza Rizvi, Assistant Profesor
    Chirped and Dipole Soliton in Nonlinear Negative Index Materials A wave which propagates without changing its shape and speed is known as soliton. 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 ton
