Reversal of circular Bragg phenomenon in ferrocholesteric materials with negative real permittivities and permeabilities
A reversal of the Bragg phenomenon is shown to exist theoretically in a right/left-handed ferrocholesteric slab with negative real permittivitics and permeabilities. In addition to the promise of isotropic homogeneous materials with negative real permittivities and permeabilities for unexpected applications (e.g., distortion-free lenses), the presented results underscore the similar potential of anisotropic inhomogeneous materials with analogous characteristics.
