Electromagnetic angular momentum in anisotropic media and Beth's torque

open access: yesPhysics Open, 2022
The interaction of radiation with material media is a very active area of research, in particular the interaction with new exotic materials. However, we find several controversies in this field, like the Abraham-Minkowski controversy, or the attribution of angular momentum to quasi-static fields.In the present work we show that besides the ...
