A Comprehensive Analysis of the Absorption Spectrum of Conducting Ferromagnetic Wires

摘要

A detailed analysis of the absorption spectrum of conductive ferromagnetic wires is presented. The absorption spectrum is computed from the solution to the scattering problem, and circuit models are formulated to clarify the interplay between losses, skin effect, and wire geometry. Both infinitely long wires and the axial resonances introduced by finite-length wires are considered. The theoretical results are validated experimentally through measurements within a metallic rectangular waveguide.
