综述了有效参数为负实部的人工被动材料材料本构参数的基本物理限制。结果表明，具有负色散参数的假设材料中的场解是不稳定的。讨论了具有非色散负参数的活性超材料中的能量密度和场解。
Basic physical limitations on the material constitutive parameters of artificial passive materials with negative real parts of the effective parameters are reviewed. It is shown that field solutions in hypothetical materials with negative and nondispersive parameters are unstable. The energy density and field solutions in active metamaterials with nondispersive negative parameters are also considered
