A negative index of refraction due to three-dimensional chirality is demonstrated for abilayered metamaterial based on pairs of mutually twisted planar metal patterns in parallel planes, which alsoshows negative electric and magnetic responses and exceptionally strong optical activity and circular dichro-ism.
AMAZONITE FELDSPAR PHYSICAL PROPERTIES. Twinning: twinned according to the albite twin law with {010} the twin plane, and the pericline twin law with b the twin axis.
