Abstract
We generalize the vacuum form reduction – a technique made possible due to the dimensional grading of
Clifford (geometric) algebra – for the study of moving bi-isotropic media. The advantage of this technique is that
a moving medium is studied in a similar way as vacuum – although in a fictitious spacetime. It is shown that the
Bohren decomposition is applicable to moving chiral media: we can apply the vacuum form reduction, separately
to each one of the two equivalent isotropic media of the Bohren decomposition, to obtain the two isonormal
waves of a moving chiral medium in the lab frame.
