Abstract: A multilayer conductor includes a conductor layer and a dielectric layer on the conductor layer. The dielectric layer includes a polymer composition having a dissipation factor (Df) of less than 0.001 and includes a cyclic olefin copolymer, a transoctenamer rubber, syndiotactic polystyrene, a polymethylpentene olefin copolymer, or a combination thereof. The materials described herein can advantageously provide an improved adhesive strength between the conductor and the dielectric layer. Methods for the manufacture of the multilayer conductor are also described. The multilayer conductor can be useful in the preparation of magnetic self-resonant structures.
