Nonlinear waves with negative phase velocity.

Recently, waves propagating with negative phase velocity [simply called antiwaves (AWs)] have attracted great attention in the area of nonlinear oscillatory systems. In the present work we investigate the parameter conditions for AWs. So far AWs have been revealed from systems slightly beyond Hopf bifurcation or some other instabilities, and from some wave sources with certain restricted freque...

Feeding and dissipative waves in fracture and phase transition II. Phase-transition waves

Discrete and homogeneous models of a structured material are considered to resolve di0culties in the analysis of dynamic phase transition. The discrete model is a chain consisting of particles connected by massless bonds, while the continuous model is represented by a partial di3erential equation with higher than the second order of coordinate derivatives. The macrolevel constitutive law is rep...
