人工材料を用いる電磁波吸収体?電磁遮ヘい材?透過材

摘要

In this article,an Electromagnetic (EM) wave absorber,EM shielding material,and EM controlling material using artificially designed materials proposed by the author are described.For the artificially designed materials,finite-and infinite-length metal-wire-array sheets and periodically perforated metal plates are used here.Laminated structures consisting of the sheets and dielectric material are proposed.The reflection and transmission characteristics of the structures can be controlled by changing metal wire parameters such as the wire length,spacing gaps between the wires,and the dielectric material's thickness and relative permittivity.The reflection and transmission characteristics are evaluated by measurements in free space and by FDTD calculations.
