Proceeding from the solution to the linear spectral problem for defini
te cooperative media containing an isolated nondegenerate Mol se criti
cal point, the dispersion equations are constructed analytically close
to this point. These equations, which are applied for obtaining the m
odified Ginzburg-Landau equations, as well as the specially performed
electrodynamic experiments, enable us to construct a new model of dete
rministic chaos close to the Morse point.
