1. Limitadores de potencia seletivas em frequencia usando a geração subharmonica de ondas spin em meteriais ferrimagneticos
A review of the linear and non linear theories applied to ferrimagnetic materials is presented with the objective of providing a better understanding of the phenomena occuring in Frequency Selective Power Limiters (LPSF s) operating in the coincidence and subsidiary resonance modes. In addition, it is shown that the limiters operating band pass filters when
