A novel radar‐absorbing‐material based on EBG structure

A novel ultra-thin radar-absorbing material (RAM) using metamaterials is presented and the absorption performance is examined. Due to the high-impedance property of the metamaterials, the thickness of the RAM is about several tenths of the center wavelength of the absorption band, which is considerably thinner than conventional absorbers. The absorption bandwidth of the RAM is about several hundred megahertz. © 2005 Wiley Periodicals, Inc.
