An epoxy-bonded LiNb03-YIG-LiNb03 composite structure has been constructed and operated as a magnetoelastic Rayleigh wave convolver with 50-MHz input signals. The acoustic signals were propagated on a (110) YIG surface and the convolution characteristics were studied as a function of the magnitude and direction of the applied magnetic field. Nonuniform demagnetizing fields limited convolution pulses to less than 1.5 /-Lsec duration. Relatively efficient operation was observed corresponding to an internal efficiency F int of -53 dBm
