Physics of the spin wave–electromagnetic (EM) interaction is investigated for RF limiter applications, by looking at the magnetization $M$ and its deviation $\Delta M$ through equations of motion. Exchange effects are examined, and a complete magnetodynamics equation is developed and looked at for both the fundamental- and second-harmonic frequencies. Nonlinear conversion of energy occurs between the first and second harmonics. It is shown here that the usual operating frequencies for RF limiters, in the range of 1.5–15-GHz frequencies, can be lifted up into the much higher frequencies of the 40–60-GHz range by a new formula developed from fundamental spin wave–EM interactions in magnetic material characterized by a magnetization $M$. The treatment is self-contained in which all of the information needed to understand the magnetics aspect for RF applications is provided. [ABSTRACT FROM AUTHOR] |
