Abstract
The anomalous dispersion in pseudochiral media is theoretically investigated, with emphasis on the features of negative refraction and backward wave. In these media, material properties are characterized by symmetric magnetoelectric tensors with zero diagonal elements. Strong magnetoelectric couplings in such media give rise to a special form of petal-like dispersion curves, which support negative refraction and backward wave over a certain range of the angle of incidence. Two threshold angles in terms of the chirality parameter are given to characterize these features. © 2013 IOP Publishing Ltd.
