双曲材料作为一种新的电磁材料，不仅可以调控电磁波的传播，而且可以调控电磁波和原子之间、原子和原子之间的相互作用。本项目围绕电磁波在双曲材料中的传播与控制展开理论和实验研究。研究内容分两部分。首先，项目将研究类电磁感应透明现象中，双曲材料对电磁类原子之间近场耦合作用的调控。其次，项目将研究两类双曲材料之间的转变以及临界双曲材料中的锥形等频率面带来的新奇电磁现象和应用。项目的研究成果不仅可以帮助人们利用双曲或锥形等特殊色散关系来调控电磁波的运动，突破传统材料对电磁波功能的限制，而且对远距离能量传输器和分光器等相关器件的研制具有指导意义。

The hyperbolic metamaterials are a new kind of electromagnetic (EM) materials. They can not only tailor the propagation of EM waves, but also manipulate the interactions between EM waves and atoms as well as the interactions between different atoms. This project studies theoretically and experimentally the propagation and control of EM waves in hyperbolic metamaterials. The study contains two parts. The first part deals with the manipulation of near-field coupling between EM atomic-like resonators by hyperbolic metamaterials in the classical counterpart of electromagnetic induced transparency. The second part studies the transition between two kinds of hyperbolic metamaterials and the novel EM phenomena as well as the applications brought by the cone-shaped isofrequency surface of the critical hyperbolic metamaterials at the transition point. The achievements of this project not only help people control the flow of EM waves and break through the limitation of traditional materials on the functions of EM waves by means of the hyperbolic or cone-shaped dispersions, but also play an important role in the design of related devices including long range energy transfer device, beam splitter, etc.
