Interaction of light and matter can be controlled and manipulated by exploiting the properties of the isofrequency contours (IFCs) of a material. IFC in metamaterial/artificial anisotropic materials can be open and/or closed. The class of metamaterials with open IFC are known as hyperbolic metamaterials (HMMs)/indefinite media. HMMs support large wavevectors, which can lead to some important consequences, such as energy transfer (long range), metacavity lasers (subwavelength scale), sensors (high sensitivity), and hyperlenses (surpassing diffraction limit). Therefore, in this paper wavevector planes for media with open and closed IFCs are investigated with an aim to further differentiate them into regions supporting distinct electromagnetic modes, orientation of power, wavevector, and positive-negative phase velocities.

非耗散各向异性超材料的各种电磁模式

可以通过利用材料的等频轮廓（IFC）的特性来控制和操纵光与物质的相互作用。超材料/人造各向异性材料中的IFC可以打开和/或关闭。具有开放式IFC的超材料一类称为双曲线超材料（HMM）/不确定介质。HMM支持大的波矢，这可能导致一些重要的后果，例如能量转移（远距离），超腔激光器（亚波长标度），传感器（高灵敏度）和超透镜（超过衍射极限）。因此，在本文中，研究了具有开放式和封闭式IFC的介质的波矢平面，目的是将它们进一步区分为支持不同电磁模式，功率方向，波矢和正负相速度的区域。
