    Comments on “A set square design metamaterial absorber for X band applications”
    (Taylor & Francis, 2021-05-24) Ur Rahman, S.; Ullah, H.; Cao, Q.; Kabir Khan, M.; Ullah, Naveed; Ullah, Naveed
    In a recently published paper, Chetan Barde et al. [Barde C, Choubey A, Sinha R. A set square design metamaterial absorber for X-band applications. J Electromagn Waves Appl. 2019:1–14.] have proposed a wideband metamaterial absorber and have attempted to elaborate reflection theory for the absorptivity. They have claimed a wideband absorption rate due to ignorance of cross-polarization component of the reflected wave. They have erroneously interpreted a linear reflective polarization converter as a wideband absorber.
