1. A magneto-electric transformer, comprising:

  • a top section comprised of one or more magnetostrictive layers;

    a bottom section comprised of one or more magnetostrictive layers; and

    an elastic section comprised of one or more piezoelectric layers, said elastic section being sandwiched with a mechanical bond between said magnetic section and said electric section to form a composite structure of parallel layers, wherein a harmonic ac magnetic field is applied along the parallel layers of the composite at a mechanical resonance frequency of the bonded composite structure, there being a continuity of both magnetic and electric flux lines across said sections.
