Abstract

We have shown liquid crystals to be members of the more general class of helicoidal bianisotropic mediums (HBMs) and have discussed physical realizations of HBMs as liquid crystals, cross-linked polymer networks and solid thin films. Solutions of the time-harmonic Maxwell postulates for axial propagation in a HBM have been derived in terms of the eigenvalues and eigenvectors of a 4 × 4 matrix. We have given a procedure to obtain the response of a HBM slab to a normally incident plane wave and exemplified our analytical results by application to four mediums.
