FDTD Numerical Simulation of Absorption of Microwaves in an Unmagnetized Atmosphere Plasma

扫码查看
Numerical simulations based on the finite-difference-time-domain (FDTD) approximation to multi-fluid equations for positive ions, negative ions and electrons are used to study high frequency electromagnetic wave propagation and absorption in an unmagnetized plasma layer. The interaction between the incident high frequency wave and the plasma layer shows that the existence of negative ions and the nonlinear effect reduces the power absorption capability of the plasma. Parameter dependences of the effects are calculated and discussed.
