“…Sen et al [] proposed the applications of dromions in plasma heating and self‐focusing by manipulation of the boundary potentials. The characteristics of dromions in two‐component magnetized dusty plasma in the presence of positive ions obeying Maxwellian distribution were reported by Annou and Annou []. They illustrated the effect of magnetic field as well as dust concentration on the characteristics of DA dromions.…”

“…To the best of our knowledge, the study of DA dromions (2‐D nonlinear structures) in a magnetized dusty plasma consisting of charged particles featuring kappa distribution has not been reported so far. From the survey of literature, we have noticed that only one investigation on the study of DA dromions in magnetized two‐component (ion‐dust) dusty plasma with negatively charged dust fluid and Maxwellian positive ions has been reported by Annou and Annou []. They ignored the role of electrons and superthermality of charged particles (electrons and ions) to study the DA dromions in two‐component plasma.…”

An investigation of dust acoustic (DA) dromions in a magnetized dusty plasma consisting of inertial dust fluid, kappa‐type distributed electrons, and ions is presented. Using reductive perturbation technique, we have derived coupled nonlinear evolution equations of (2 + 1) dimensions (called Davey‐Stewartson (DS‐I) equations). Hirota bilinear method has been employed to derive the analytical solution of DS‐I equations. The solutions of such equations are exponentially localized and are called dromions. The combined effects of various physical parameters such as superthermality of charged particles, strength of magnetic field, and dust concentration have been studied on the existence regions and propagation properties of DA dromions in context with observations of POLAR satellite in the presence of superthermal particles in polar cap boundary layer region of Earth's atmosphere.
