“…[27][28][29][30][31] A steady steel cylindrical cavity of 6 cm internal diameter, with its' length adaptable to any purpose, is used almost always, as it is preferable due to its' cylindrical symmetry simplicity. The argon-plasma is usually produced due to the argon atoms inertia and its' low penetration.…”

“…The study of these waves has been done theoretically 27,28,30 by using the fluid mechanics equations and their dispersion relation, as well as the growth rate and damping, have been found. Thus, three types of dispersion relations and their growth rate are mentioned here; the first dispersion relation is the following, with the growth rate, …”

“…The imaginary part of the wave circular frequency has been actually calculated via the steady state hydrodynamic equations. 27,28 On the other hand, the wave stability on the steady state demands ω i to be near zero, whence it must be considered that the extinguishing factors press for ω i → 0.…”

“…In the present work three such examples have been given, 27,28 although the purpose of our team is to shape a full list of the models, which may be useful and easy for the experimental and theoretical researchers. Thus, the completion of the model list is the immediate future work, since the experimental confirmation is the difficult part of the completed research; this difficulty is caused by the little amount of time for the growth establishment of the rising wave, whereas this amount of time is very large for the nuclear decays; for this reason the measurements must be taken very methodically.…”

Many physical phenomena that concern the research these days are basically complicated because of being multi-parametric. Thus, their study and understanding meets with big if not unsolved obstacles. Such complicated and multi-parametric is the plasmatic state as well, where the plasma and the physical quantities that appear along with it have chaotic behavior. Many of those physical quantities change exponentially and at most times they are stabilized by presenting wavy behavior. Mostly in the transitive state rather than the steady state, the exponentially changing quantities (Growth, Damping etc) depend on each other in most cases. Thus, it is difficult to distinguish the cause from the result. The present paper attempts to help this difficult study and understanding by proposing mathematical exponential models that could relate with the study and understanding of the plasmatic wavy instability behavior. Such instabilities are already detected, understood and presented in previous publications of our laboratory. In other words, our new contribution is the study of the already known plasmatic quantities by using mathematical models (modeling and simulation). These methods are both useful and applicable in the chaotic theory. In addition, our ambition is to also conduct a list of models useful for the study of chaotic problems, such as those that appear into the plasma, starting with this paper's examples.
