Non-linear Electrostatic Waves in a Dusty Electronegative Plasma

Very recently both theoretical and experimental observations show that the presence of negative ions which occur in many space and laboratory dusty plasma situations significantly modify the charging of dust particles. It is expected that the presence of such negative ions can modify or introduce new features in the propagation of the nonlinear waves (DIA and DA) in such a dusty electronegative plasma (dusty plasma with an additional negative ion).
