The grating transducer, the dual of the meander line, is studied and its performance compared with a meander line for the excitation of magnetoelastic surface waves. A LiNbO//3-YIG-LiNbO//3 epoxy-bonded composite is used experimentally study both transducer geometries at 50 MHz. It is found that the grating transducer offers no signficant improvement in performance over the meander line. Both types of transducers have large conversion losses because of large ohmic resistance to radiation resistance ratios. Practical considerations of allowable metallization thickness for the transducers and spatially nonuniform demagnetizing fields in the substrate permit only modest reductions in the conversion losses of either type of transducer situated on materials such as YIG.
