| Abstract | ||
| The interaction between the incident, high frequency, electromagnetic waves with plasma layer shows that the existence of negative ions and the non-linear effect reduces the power absorption capability of the plasma. In this research we study and discuss all parameters of the great influence in this process depending on many important equations, like the Maxwell equations, current response of the plasma equation, multi – fluid momentum equation and the continuity equation. Numerical simulations based on the finite- difference- time- domain approximation to multi- fluid equations for the positive ions, negative ions and electrons are used to study high frequency electromagnetic waves propagation and absorption in an unmagnetized plasma layer. A good agreement in the comparison between the simulations in this work and the experimental results in the previous works is shown. | ||
