An ultra-thin hexagonal microwave metamaterial absorber is described It can absorb any polarized transverse electromagnetic wave because of its hexagonal shape. In spite of its very thin structure, almost 0.028 lambda(g), the absorber achieved 99% absorptivity at 11.35 GHz in experimental results because of the increased coupling losses, showing good agreement with simulation results. In addition, this high absorbance is unchanged for any polarized waves with the same frequency.
