special relativity - Covariant Description of Light Scattering at a fastly rotating Cylinder


Let us consider the following Gedankenexperiment:


A cylinder rotates symmetric around the z axis with angular velocity Ω and a plane wave with EBei(kxωt) gets scattered by it.



We assume to know the isotropic permittivity ϵ(ω) and permeability μ(ω) of the cylinder's material at rest. Furthermore, the cylinder is infinitely long in z-direction.


The static problem (Ω=0) can be treated in terms of Mie Theory - here, however, one will need a covariant description of the system for very fast rotations (which are assumed to be possible) causing nontrivial transformations of ϵ and μ.


Hence my question:



What is the scattering response to a plane wave on a fastly rotating cylinder?
