Abstract :
Owing to the nonlinear effect of LPE-YIG film and the energy confinement effect in the resonator, the resonant frequency of a MSSW-SER (straight edge resonator) shifts appreciably with exciting power increase. Using this principle, an experimental method is proposed to investigate the nonlinear MSSW dispersion without large excitation power. The MSSW nonlinear propagation theory is verified by experimental results
