Arbitrary Amplitude Dust Kinetic Alfvén Solitary Waves (DKASW) in a Three-Component Magnetized Plasma with Non-Thermal Electrons and Ions

The existence of arbitrary amplitude dust kinetic Alfvén wave has been studied in a three-component plasma with magnetized cold dust and non-thermally distributed ions and electrons. In order to study the non-linear behavior of dust kinetic Alfvén waves, the Sagdeev potential method is used. The existence domain of the solitary wave has been established. It is observed that only rarefactive sub-Alfvénic DKAW are generated.
