论文摘要
元材料是对具有异常光学特性的凝结问题的重要讨论之一。它们可用于调节光和波传播。天然双曲线和非凸等离子体是在这些材料中观察到的元物质的特征。在本文中，我们研究了三层光学特性（Becbe）三层光学特性，并表明该材料在THZ频率区域和非凸等等离子中具有双曲线。我们已经显示了沿双曲区域的$ q_y $轴的大部分等离子体能量传播。同样，可以看出，仅在1029.71 THZ频率中才有椭圆情况。双曲区域的起点发生在289.31 THz的频率下，这是第一个也是最狭窄的双曲线窗口。由于Becbe等离激子材料中存在更多的自由电子，因此第三个双曲线窗口中可见区域的存在会导致高血浆频率。
Meta-materials are one of the important discussions of condensed matters which have unusual optical properties. They can be used to regulate light and wave propagation. Natural hyperbolic and non-convex plasmons are the characteristics of meta-materials that are observed in these materials. In this paper, we have studied Beryllium-Graphene-Beryllium (BeCBe) three-layer optical properties and have shown this material has hyperbolic plasmon in the THz frequency region and non-convex plasmons. We have shown most of the plasmon energy propagation along the $q_y$ axis for the hyperbolic region. Also, it can be seen that there is an elliptic case only in 1029.71 THz frequency. The starting point of the hyperbolic region occurs at the frequency of 289.31 THz, which is the first and the narrowest hyperbolic window. Due to the existence of far more free electrons in the BeCBe plasmonic material, the presence of the visible region in the third hyperbolic window causes a high plasma frequency.
