Skin effect suppression for millimeter-wave frequencies through manipulation of permeability

Abstract

A new device strategy for suppressing unwanted skin effect in coplanar transmission lines at frequencies beyond 20 GHz is presented. Utilization of the anti-resonance point as a source of imaginary permeability to suppress the skin effect is proposed. This idea is backed up by Kramers-Kronig and published experiments. The principle is independent of Landau–Lifshitz-Gilbert magnetic precession damping. The present work contributes both a greater understanding of skin effect manipulation and a method for obtaining zero skin effect using known laminate materials.
