论文摘要
在本文中，我们揭示了各向异性超材料中三 - 和四纤维骨的形成背后的物理，而无需磁性耦合，并描述了由于血浆和磁性布洛克型高量高螺旋体杂交引起的双曲线分散体中的抗跨性分裂现象。这大大加深了对高量极化子的理解以及K空间中光学等频表面的拓扑结构，并将在光学纳米分辨率成像，发射速率和方向性控制中找到应用。为此，我们开发了一系列针对双异构材料的理论光学技术的新技术，包括折射操作方法的二次索引，适合研究具有有限的折射指数的高k极性子，以及在普通的bianisotropic媒体中具有特征性基质的显式表达。我们介绍了各向异性均质介质的电和磁反应的空间分层方法，以分析基础的BLOCH波。我们认为，这里开发的形式主义对未来各向异性和双异构介质的理论光学领域的研究人员很有用。
In this paper we reveal the physics behind the formation of tri- and tetra-hyperbolic phases in anisotropic metamaterials without magnetoelectric coupling and describe the anti-crossing splitting phenomenon in the hyperbolic dispersion which arises due to the hybridization of the plasmonic and magnetic Bloch high-k polaritons. This considerably deepens the understanding of the high-k polaritons and the topology of the optical iso-frequency surfaces in k-space and will find applications in optical nano-resolution imaging and emission rate and directivity control. To accomplish this, we develop a range of new techniques of theoretical optics for bianisotropic materials, including the quadratic index of refraction operator method, suitable to study the high-k polaritons with finite indices of refraction and the explicit expression for the characteristic matrix in generic bianisotropic media. We introduce the spatial stratification approach for the electric and magnetic responses of anisotropic homogeneous media to analyze the underlying Bloch waves. We believe that the formalisms developed here can be useful for the researchers in the field of theoretical optics of anisotropic and bianisotropic media in the future.
