Abstract

The authors have proposed an Ultrabroadband Metamaterial Microwave Absorber. The authors have claimed that the proposed structure is metamaterial absorber. We have recognized that the designed structure is not a metamaterial absorber because of ignorance of cross-polarized reflection coefficient. The designed structure is polarization convertor because the proposed unit cell has an-isotropic geometry.
