The parameter regimes for the integrable cases of the coupled mode equations have been explicitly obtained. For positive group dispersion of the upper--hybrid waves, the relevant governing equations lead to a novel Hamiltonian where the kinetic energy is not positive definite.","authors_text":"Ahmedabad-380009, India), Navrangpura, N.N.
