用数值模拟方法研究了被介电层分隔的相互扭曲金属（银）交叉的周期对的性质。结果表明，在红外通信波长（1.55微米）处存在异常强的偏振旋转和圆二色性、负磁导率和负折射率。
The properties of periodic pairs of mutually twisted metallic (silver) crosses separated by dielectric layer have been investigated by numerical simulation. The results show that the exceptionally strong polarization rotation and circular dichroism, negative permeability and negative refractive index are found at the infrared communication wavelength (1.55 microm).
