We fabricated a polarization-dependent terahertz (THz) metamaterial absorber consisted of a metal film, a dielectric spacer and a metal pattern layer. The measured absorptivity for x-polarized wave is about 0.9 at 1.42THz, and that for y-polarized wave is about 0.87 at 2.15THz. The full width at half maximum (FWHM) of peaks at 1.42THz and 2.15THz are about 0.23THz and 0.38THz, respectively. The experimental...
