摘要：
Operation of ferrimagnetic frequency-selective limiters (FSL) is based on non-linear absorption in magnetized ferrite films at RF/microwave power levels exceeding some threshold. A new phenomenological model of non-linear loss in a ferrite medium has been proposed, and it has been implemented in an efficient numerical algorithm for an FSL performance prediction.
