本文研究了平行偏置结构下磁弹性Rayleigh波在YIG基片上的传播特性，偏置场与基片相切，平行于传播方向。YIG表面被认为是机械自由的，并且要么邻接真空（未金属化配置），要么被薄的完美导电金属膜（金属化配置）电短路。ME瑞利波被发现是在静磁体波谱近似给出的频率谱之外的束缚表面波，并且是其中的泄漏型。通过改变泄漏波谱上的频率（或等效的偏置场），可以控制能量泄漏到衬底中的方向与表面波传播方向成180°角。
The propagation characteristics of magnetoelastic (ME) Rayleigh waves on a YIG substrate are treated for the parallel bias configuration, wherein the bias field is tangential to the substrate and parallel to the direction of propagation. The YIG surface is considered to be mechanically free and either adjoined to vacuum (unmetallized configuration) or electrically shorted by a thin perfectly conducting metallic film (metallized configuration). The ME Rayleigh waves are found to be bound surface waves outside of a spectrum of frequencies given approximately by the magnetostatic bulk‐wave spectrum, and of the leaky type within it. By varying the frequency (or equivalently the bias field) over the leaky‐wave spectrum, the direction of energy leakage into the substrate may be controlled over an angle of 180° from the direction of surface‐wave propagation.
