Design of electromagnetic wave absorber by use of metal wire array sheet

In this paper, properties of artificially-designed materials and their applications in electromagnetic (EM) wave absorber are discussed. First, EM-wave absorber composed of the straight length wire array sheet and a ferrite-powder/rubber mixture plate is investigated. The absorbing characteristics of the absorber using the wire array sheet can be matched at around the resonant frequency of the sheet. Next, EM absorbers using the wire array sheet having two resonant frequencies are proposed here.
