Abstract

In a paper published in Optics Communications, Liu et al. presented a flexible ultra-wideband microwave metamaterial absorber with multiple perfect absorption peaks based on the split square ring. Unfortunately, the cross-polarization reflection was omitted, and then the proposed absorber’s absorp-tion rate was not calculated in a correct way. In this paper, we reveal the problem of the paper. Our results show that the proposed design owns a structure with poor absorptive performance.
