Abstract
A method of fabricating a multiferroic antenna element may include providing a electroelastic substrate to transform mechanical oscillations into an acoustic wave, providing a resonator assembly on a surface of the electroelastic substrate where the resonator assembly includes a plurality of magnetoelastic resonators that transform an electromagnetic wave into mechanical oscillations corresponding to a frequency of the electromagnetic wave, and providing an interdigitated electrode assembly at a portion of the electroelastic substrate to convert the acoustic wave into an electrical signal preserving information associated with the frequency of the electromagnetic wave.
