SOLITARY WAVES IN DISCRETE MEDIA WITH ANOMALOUS COMPRESSIBILITY AND SIMILAR TO SONIC VACUUM

Propagation of deformation pulses in significantly nonlinear media wit h inner structure where there is no linear part in interaction force b etween neighboring structure elements is considered. This makes imposs ible the application of traditional wave equation or developed earlier approaches wherein nonlinearity serves as a small correction and requ ires the development of a qualitatively new nonlinear wave dynamics.
