Studying nonlinear waves in Dusty Plasma Medium

In this work we studied the phenomena associated to the interaction of nonlinear plasma waves with charged bodies. Nonlinear waves and structures generated by plasma flows are far from being understood in simulations and experimental matters. These phenomena resemble the structure formation in astrophysical scenarios therefore their fundamental properties must be firmly understood using laboratory settings [1]. We have studied nonlinear structure using a dusty plasma medium at Eastern Michigan University plasma lab. A dusty plasma medium provides easy access to study linear and nonlinear waves due to its diagnostic convenience over electron-ion plasma [2]. We complemented our experiments with theoretical calculation/simulation where we solved a set of fluid equations to extract the properties of nonlinear plasma waves and their interaction with stationary charged bodies. A detailed comparison of the experiment and simulation results will be presented at the conference.
