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 surf

A theoretical derivation of theQ-factor of an MSW delay-line based oscillator is presented which is based on a rigorous, classical definition of theQ-factor of a resonator. The theory takes into account (1) the propagation loss in the delay line, (2)

The experimental results for the delay time of a signal propagating through a thick fluid layer as a function of thickness is given. A theoretical analysis of the interference of the normal modes of a thick layer is presented and it is shown that the
