Abstract :
A 1-10 GHz magnetostatic wave (MSW) phase shifter that uses a single crystal yttrium iron garnet (YIG) and lead zirconium titanate (PZT) layered structure as a medium for MSW propagation is studied. The structure provides electric field control of the phase shift due to magnetoelectric interaction at the YIG-PZT interface. Phase shifts of the order of a radian have been obtained for nominal electric fields.
