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.

Abstract: A trilayer polymer film includes a core layer and first and second outer layers on opposing surfaces of the core layer. The compositions of each of the layers is as described herein, wherein the first outer layer and the second outer layer each independently include a fluoropolymer having a melting temperature that is at least 15° C. less than a melting temperature of the core layer. The film can be useful in the preparation of multilayer conductors and magnetic self-resonant structures.
