摘要

We present a progressive overview of diverse plasma fireball sheath (PFS) structures, sheath-induced collective phenomena, and associated instability excitation processes, illustratively. The possible damping mechanisms of the excited instabilities in conventional PFS systems are specially highlighted. An experimental glimpse of both the regular fireball (RFB) and inverted fireball (IFB) classes is manifested. We draw special distinctions between (a) RFB and IFB, (b) laboratory and astrocosmic fireballs, and (c) RFB and IFB sheath formation mechanisms. A portrayal of the chronological development of PFS research investigations since the inception of plasma-electrode coupling studies is offered alongside their key properties. It outlines a glimpse of current RFB and IFB investigations in both laboratory and astrospace plasmas. Finally, the non-trivial future PFS-based applications in both theoretical and applied perspectives are emphasized.
