No, it is not typical physics paper (physicist here). Little is clearly defined. E.g. phase shift in what --- if the meaning is the same as in standard EM/QED, what is it the authors exactly propose (probably they don't work in this framework if they reject photon number change), and can the replacement they propose predict something correctly? Overall, the paper reads like a word salad, as the explanations are all over the place. At least the second author of the paper is known also for other bunk, so grains of salt recommended.
