    "abstract": "A structurally right/left-handed ferrocholesteric slab with negative real\npermittivities and permeabilities is theoretically shown to display the Bragg\nphenomenon on axial excitation as if it were a structurally left/right-handed\nferrocholesteric slab with positive real permittivities and positive real\npermeabilities. In addition to the promise of isotropic homogeneous materials\nwith negative real permittivities and permeabilities for unexpected\napplications, the presented results underscore the similar potential of\nanisotropic nonhomogeneous materials with analogous characteristics.",
