Metallic Wire Structures Under a Moderate Electromagnetic Field

Abstract

Metallic wire structures from simple to complex have long been used as absorbers of electromagnetic radiation. As we discussed in previous chapters, the response of the wire structure is characterized by a series of resonances. In our approach, we introduce new variables which consist of localized electric fields at the ends and junctions of the wire structures. Near the resonance frequencies for optimum absorption the electric fields at the ends of the wire structure are generally larger by many orders of magnitude than the magnitude of the external electric field.
