摘要: This numerical study isolates some of the experimentally interesting properties large amplitude spatially localized electric fields in Langmuir frequency range which are described by nonlinear Schrodinger equation with full exponential nonlinearity retained. The steady state eigenvalues and wavefunctions calculated their compared small soliton solutions. A variety time dependent effects investigated both bounded unbounded geometries. Some these are: evolution initial standing waves; collisional properties; pumping stationary, moving, colliding solitons a uniform external field.
