... We consider a set of invariant travelling wave (TW) solutions for two modelling systems,   simulating long non-linear waves propagation in structured media. Using the methods of   local non-linear analysis and numerical simulation, we show that in both cases the set of   TW solutions contains localized soliton-like regimes, corresponding to homoclinic loops   of three-dimensional dynamical systems obtained from the initial systems of PDE through   the group theory reduction. ...
