Abstract:The debate over whether light’s momentum within a medium is accurately described by Abraham or Minkowski formulation has persisted for over a century. To our knowledge, this dilemma has not been explored within the context of Smith–Purcell radiation. This is because, in conventional Smith–Purcell radiation scenarios, the refractive index is equal to one, leading both the Abraham and Minkowski formulations to yield identical results. Here, we investigate the Abraham–Minkowski dilemma within the realm of Smith–P… Show more
