“…Figures 7 and 8 show a decrease of phase shift as the structure parameter increases. The reason for the decrease in the phase shift value is due to the phase shift being related to the dispersion coefficient B, which in turn is related to the structure parameter as shown in relation (21). In other words, the phase shifts of solitons after interaction increase as the coupling strength between dust particles increases.…”

The effect of the structure parameter on the compressibility of dust grains and soliton behavior in a dusty plasma system consisting of Maxwellian electrons, ions, and dust grains charged with a negative charge has been studied. In the theoretical study, a reductive perturbation technique was used to derive the Korteweg-de Vries (KdV) equation and employ the Hirota bilinear method to obtain multisoliton solution. It is found that coupling and structure parameters have a clear effect on the compressibility. These changes in the compressibility affected the amplitude and width of interactive solitons, in addition to the phase shifts resulting from the interaction. These results can be used to understand the behavior of solitary waves that occur in various natural and laboratory plasma environments with dust impurity situations.
