Lie symmetry analysis and group invariant solutions of the nonlinear Helmholtz equation

K. Sakkaravarthi, A. G. Johnpillai, A. Durga Devi +2

We consider the nonlinear Helmholtz (NLH) equation describing the beam propagation in a planar waveguide with Kerr-like nonlinearity under non-paraxial approximation. By applying t…
