Abstract :
Considering electron temperature arising time, new concepts of safe pulse length threshold and safe amplitude threshold are put forward. Combined with electron kinetic equation, electron energy equation and Maxwell equations, a FDTD method is proposed to analyze the nonlinear propagation characteristics of high power microwave in lower ionosphere. And also, the relationship of safe pulse length threshold, safe amplitude threshold with frequency, electron number density and collision frequency are discussed.
