Reflection and transmission by a uniaxially bi-anisotropic slab under normal incidence of plane waves

In this paper plane-wave reflection and transmission phenomena in slabs of uniaxial bi-anisotropic media are theoretically considered. The axis direction is in the interface plane and normal incidence of the plane wave is assumed. Chiral reciprocal slabs and a special class of non-reciprocal media are covered. The study is relevant to recent experimental studies of arrays of parallel spirals. The present theory gives an analytical model of such artificial bi-anisotropic media.
