Study on electromagnetic properties of dusty plasma
Abstract
In the practical application of plasma, dusty plasma has been increasing recognized in various research fields such as astrophysics, space communication, aerospace, and industrial production. Significant phenomena associated with dusty plasma include aircraft reentry processes, communication interference due to microwave abnormal attenuation in rocket tail flames, and summertime anomalies in ionospheric echo signals. Dusty plasma is characterized by micro or nano-sized particles suspended within a plasma medium. These particles interact with other charged particles in the plasma, exhibiting unique electromagnetic properties across different physical environments. This paper provides an overview of the historical trajectory of dusty plasma research, its current research directions, fundamental electromagnetic attributes, and interaction mechanisms with electromagnetic waves. It also highlights challenges faced in both theoretical and experimental analyses, particularly the imprecision in theoretical calculations for inhomogeneous dusty plasma, inconsistencies between theoretical and experimental outcomes under specific conditions, and the complexities associated with conducting experiments on dusty plasma-electromagnetic wave interactions in particular settings. The paper concludes by offering insights into potential future trajectories for dusty plasma research, focusing on its interactions with electromagnetic waves.
