In a recent publication by Xiong et al. [J. Appl. Phys. 114, 064109 (2013)], a linear cross-polarizer is erroneously interpreted as a broadband absorber with a claimed absorptivity above 90% over a frequency range of 8.3721 GHz. In this article, the authors have presented an investigative study demo...
