Abstract

Recently Deyo et al. [\prb {\bf 106}, 104502 (2022)] suggested that the surface resistance $R_{s} (H_{0})$ 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. \cite{corn} give incorrect field and temperature dependencies of $R_{s} (T, H_{0})$ .
