论文摘要
我们得出与通过双曲线超材料（HMM）的电磁波相关的能量密度。研究了两种类型的HMM。通过将色散和吸收的HMM视为有效的单轴晶体，我们发现在电磁波的影响下，I型（II型）HMM在垂直于光轴和光轴的方向上的响应分别与Lorentz（Drude）（Drude）和Drude（Lorentz）媒体相似。提出了数值示例，以揭示两种HMMS的方向依赖性储能能力的一般特征。
We derive the energy density associated with an electromagnetic wave passing through a hyperbolic metamaterial (HMM). Both types of HMMs are studied. By considering a dispersive and absorbing HMM as an effective uniaxial crystal, we find that under the influence of an electromagnetic wave, the response of type I (type II) HMM in the directions perpendicular to and parallel to the optical axis are similar to those of Lorentz (Drude) and Drude (Lorentz) media, respectively. Numerical examples are presented to reveal the general characteristics of the direction-dependent energy storage capacity of both types of HMMs.
