摘要: Abstract Propagation of plasma-acoustic wave has been studied in magnetized plasma contaminated with dust charged grains. It shown that, because the configuration charge fluctuation, pseudopotential method fails to derive nonlinear equation. We thus exercise an alternate approach yield equation form Sagdeev-like potential which enables success study waves. Again a modified mathematical formalism known as tanh-method merit evaluate soliton features relation its expectation space. The finding solitary waves along other exciting formation shock-like wave, radiation propagation. results have more realistic interpretation showing explicitly interaction magnetic field and impurity caused by variation.
