Comments on: “A perspective on impedance matching and resonance absorption mechanism for electromagnetic wave absorbing” by Hou et al. [Carbon 222 (2024) 118935]

Vollständiger Abstract

Worum geht es in dieser Arbeit?

This is a comment on the problems of the paper by Hou et al., which are related to wrong theories dominated in current research of microwave absorption. The problems involve the confusion between a film and a material represented by using the film parameter reflection loss to characterize the material, the wrong impedance theory, the wrong quarter wavelength theory, and the wrong absorption mechanism for the film. The wrong theories can be corrected easily from principles not beyond a college education and have already been clarified by several papers from different perspectives in a number of journals. However, the papers using these wrong theories are continuing to be published in huge quantities without mentioning the opposite views, and further works on the subject have often been rejected even without external review. Thus, a commenting letter is necessary to draw attention.
