Abstract: 

In recent years, the high-voltage pulse devices using nonlinear properties of ferrite have received more attention. For the analysis of this kind of objects, the 2D numerical modeling technology of nonlinear saturated ferrites by FDTD method has been developed. Landau–Lifshitz equation, which describes ferrite dynamics, is solved by Runge–Kutte method and unknown components of electromagnetic fields are calculated by using linear interpolation. This method has been used to analyze oscillation forming in coaxial line partially filled with ferrite magnetized by external magnetic field. The numerical results are in agreement with the experimental data
Keywords: coaxial line, finite difference method in time domain, high-voltage impulse, Landau–Lifshitz equation, Maxwell equation, oscillations, Runge–Kutte method, saturated ferrite
