ABSTRACT
Wave plasma interaction has been widely investigated, especially with plasmas that are in steady state, inhomogeneous, and nonmagnetic in nature [1-7]. Some of the observed consequences are generation of high-energy electron bunches [1,2], excitation of temporal plasma-wave echoes in the ion wave regime [3], excitation of ion-wave wake field [4], large-amplitude electron plasma wave (EPW)-based plasma accelerators [5,6], and self-generation of magnetic fields [7]. The propagation of electromagnetic (EM) waves through temporally growing plasmas has also been analyzed, mainly in theory [8-10], including the study of dynamic behavior of microwaves through a gaseous medium that get ionized in the incident wave field [10]. It is shown that the waves can propagate through plasmas that are overdense in the steady-state approximation [9-11]. There are reports on the observation of charge oscillations in preformed steady-state plasmas subjected to an external electric field [12-14] where the plasma is produced by a different source. The plasma oscillations are analyzed in collision-free and fully ionized regimes in understanding the underlying phenomena [12-14].
