讨论了一种介电常数和磁导率均为零的手征材料模型。这种材料被我们称为“手性虚无”。结果表明，这种奇异的材料可以实现为一个小的螺旋夹杂物的混合物。分析了这种介质中的波解和能量。证明了手征虚无中的非寻常波是后向波。本文还讨论了波在手征无界面上的反射和折射。它示出，一个线偏振波垂直入射到这个界面上产生的波的“驻波”和相同的波在斜入射的情况下，导致两个折射波，其中一个与异常折射。
A model for a chiral material in which both the permittivity and permeability are equal to zero is discussed. Such a material is referred by us as a "chiral nihility". It is shown that this exotic material can be realized as a mixture of small helical inclusions. Wave solutions and energy in such a medium are analyzed. It is shown that an extraordinary wave in chiral nihility is a backward wave. Wave reflection and refraction on a chiral nihility interface are also considered. It is shown that a linearly polarized wave normally incident onto this interface produces a wave of "standing phase" and the same wave in the case of oblique incidence causes two refracted waves, one of them with an anomalous refraction.
