摘要：
Simple approximate analytical expressions for the radiation resistance of meander line and grating transducers for magnetoelastic surface wave transduction on YIG are developed. The standard simplifying assumptions of weak magnetoelastic coupling and the magnetostatic approximation are employed. in addition, the surface wave is heuristically modeled as a plane shear wave and the inhomogeneous elastic equation of motion is solved in the coupled mode approximation. The approximate expressions for the meander line radiation resistance compares well with a more exact numerical treatment done by other investigators.
