X-Band Ferrite Microstrip Limiter Based on Improved Nonlinear Loss Model for High-Power Microwave Application

An improved ferrite nonlinear (NL) loss theory is developed for polycrystal ferrite microstrip limiters upon the high-power microwave (HPM) environment. The NL critical threshold equation and equivalent loss model are derived from the field coupling mechanism between spin waves and microwave pulse....

Summary:An improved ferrite nonlinear (NL) loss theory is developed for polycrystal ferrite microstrip limiters upon the high-power microwave (HPM) environment. The NL critical threshold equation and equivalent loss model are derived from the field coupling mechanism between spin waves and microwave pulse. Thus, the equivalent NL loss behavior with the microwave waveform parameters (pulse duration and power) is implanted in the ferrite limiter model to perform the numerical simulation through the commercial electromagnetic tool. The measured limiting data at pulse duration with 60, 80, 100, and 200 ns are in good agreement with the equivalent simulation results.
