摘要

A damped nonlinear Schrödinger (DNLS) equation with damped properties has been studied via a nonthermal dusty collisional plasma model. The effects of collisional frequency and nonthermal electrons on the damped coefficient have been studied. It has been noted that the stability and instability conditions in this mode are directly impacted by the dispersion and nonlinearity coefficients. The growth rate characteristics are influenced by collision frequencies and nonthermal parameters. It was reported that the critical growth rate depends mainly on collision frequencies and nonthermal parameters.
