FDTD ANALYSIS OF NONLINEAR MAGNETIZED FERRITES: SIMULATION OF OSCILLATION FORMING IN COAXIAL LINE WITH FERRITE
RÉSUMÉ
In recent years, high-voltage pulse devices utilizing the nonlinear properties of ferrite have received more attention. The analysis of such objects is performed by a 2D numerical FDTD-based simulation of nonlinear saturated ferrites. The Landau–Lifshitz equation, which describes ferrite dynamics, is solved by the Runge–Kutte method, while linear interpolation is applied to find unknown components of electromagnetic fields. This technique has been used to simulate oscillation forming in coaxial line partially filled with ferrite being magnetized by a longitudinal magnetic field. The numerical results are in agreement with the experimental data.
