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....
