手性光学Tamm状态在介质的边界与螺旋对称的介电张量[俄语]
Chiral optical Tamm states at the boundary of the medium with helical symmetry of the dielectric tensor [In Russian]
摘要：
在具有连续螺旋对称介质张量的手征介质边界上，用解析和数值方法描述了一种新的光学态。切向波数假定为零。这种状态似乎局限于边界附近。它不会沿着这个边界传递能量，并且随着离边界的距离呈指数下降。在接近螺旋节距的波长处，对应于光子带隙，场穿透到手性介质中被阻挡。在边界附近的光的偏振具有与螺旋介质相同的手征符号。结果表明，均匀的环境，或基板必须表现出各向异性的金属反射。状态的光谱表现由界面处光轴之间的角度确定。一个现实的例子被认为是在一个胆甾相液晶和金属-介电各向异性纳米复合材料的边界。
英文摘要：
A new optical state is described both analytically and numerically at the boundary of a chiral medium with continuous helical symmetry of the dielectric tensor. The tangential wave number is assumed to be zero. The state appears to be localized near the boundary. It does not transfer energy along this boundary and falls off exponentially with the distance from the boundary. The field penetration into chiral medium is blocked at wavelengths close to the helical pitch and corresponding to the photonic band gap. The polarization of light near the boundary has the same sign of chirality as the helical medium. It is shown that the homogeneous environment, or the substrate must exhibit the anisotropic metallic reflection. Spectral manifestation of the state is determined by the angle between the optical axes at the interface. A realistic example is considered at the boundary of a cholesteric liquid crystal and a metal-dielectric anisotropic nanocomposite.
