Dynamic of ion density perturbations observed in a microwave-plasma interaction
- Department of Physics, Dhaka University of Engineering and Technology, Gazipur 1700 (Bangladesh)
The dynamical behavior of ion density perturbations propagated at low-frequency wave nature is experimentally observed in microwave-plasma interaction. An unmagnetized, inhomogeneous laboratory plasma irradiated by an obliquely incident microwave with maximum power P=10 kW and pulse width approximately ion plasma period ({tau}{sub pi}{approx_equal}2{pi}/{omega}{sub pi}) is studied. The p-polarized electric-field component of the interacted microwave of frequency {omega}{sub 0} leads to a nonlinear phenomenon driven by the ponderomotive force by the process of resonance absorption at the critical layer where {omega}{sub 0}={omega}{sub p} is satisfied. The nonlinear ion density perturbations are created from the resonant layer and propagated to an underdense plasma as an electrostatic wave nature.
