在包含碳化硅核壳微球的向列相液晶中
理论计算发现在13~13.2 μm中红外波段范围出现了负折射率。由于强烈声子激化共振产生大的介电常数
碳化硅微球在13.1 μm附近产生负磁导率。通过确定壳层材料的等离子参数
获得了负折射率。电磁模拟解释了负介电常数和负磁导率产生的机理。
The negative refractive index has been demonstrated theoretically in nematic liquid crystal consisting of randomly dispersive silicon carbide (SiC) core-shell microspheres in 13~13.2 μm mid-infrared wavelength range. Due to large permittivity of SiC induced by phonon polaritonic resonance
the collections of SiC microspheres produce negative permeability near 13.1 μm. By adjusting reasonable shell parameters
negative index liquid crystal is formed. Electromagnetic simulations show the mechanism for the negative permittivity and negative permeability.
