Here, a recent article [McAlister et al., J. Appl. Phys. 122, 144501 (2017)] claims to show the existence of "new'' higher order re-entrant post modes. Indeed, such modes do exist and are known to scientists and engineers for a very long time as modes of a foreshortened quarter-wave coaxial resonator. It is a textbook problem. In this comment, I briefly review the higher order modes in such cavities and provide relevant references.
