Abstract

In recent days, we read a paper called “Design of a Quad-Band Wide-Angle Microwave Metamaterial Absorber”, which was written by Ren et al. In such report, Ren et al. proposed a quad-band wide-angle absorber based on a metallic hexagonal patch layer. The absorption peaks are located at 6.8 GHz, 8.24 GHz, 11.24 GHz, and 12.7 GHz, whose absorptivity values are 97.2%, 95.2%, 97.7%, and 98.5%, respectively. However, we verified that the results which were given by Ren et al. are wrong because they ignored the polarization conversion. The proposed quad-band metamaterial absorber (QBMA) is not an absorber.
