Abstract

Recently Deyo et al. [\prb \bf 106, 104502 (2022)] suggested that the surface resistance R_s(H₀) of a superconductor under strong electromagnetic field can be affected by field-induced quasiparticle bound states at the surface. This Comment shows that the existence of such bound states and their contribution to R_s are not substantiated and the phenomenological models of Ref. \citecorn give incorrect field and temperature dependencies of R_s(T,H₀).
