Abstract :
A novel ultra-thin radar-absorbing material (RAM) using metamaterials is presented, and the absorption performance is examined. Owing to the high-impedance property of the metamaterials, the thickness of the RAM is about several tenths of the centre wavelength of the absorption band, considerably thinner than conventional absorbers. The absorption bandwidth of the RAM is about several hundred megahertz.
