摘要:
The insertion loss for the magnetic waves on a periodically corrugated YIG film magnetized normal to the film surface is deduced from the solution of the full magnetostatic boundary‐value problem taking into account the effect of the finite linewidth of the ferromagnetic resonance. It is found that the contribution to the insertion loss due to the distributed reflection and the mode conversion caused by the periodic surface corrugation is decreased as the resonance linewidth is increased.
