Inexplicability of the Beth’s Experiment Within the Framework of Maxwell's Electrodynamics

Authors: R. I. Khrapko

It is shown that the electromagnetic field in the well-known Beth's experiment contains no linear momentum. This means that the angular momentum of the field in the Beth’s experiment is zero, since the angular momentum, by definition, is the moment of the linear momentum. Nevertheless, the half-wave plate in the Beth’s experiment receives an angular momentum from the field, which, by definition, does not have this angular momentum. This means that the definition of the angular momentum of an electromagnetic field should be changed to explain the Beth’s experiment. The angular momentum of an electromagnetic field contains a spin term that does not depend on linear momentum.
