论文摘要
双曲线偏振层与THZ等离子体学的杂交吸引了极大的关注，因为它在该地区具有引人入胜的应用。但是，为了有效地增强这些耦合模式的性能，一种方法是在异质结构中使用智能材料。在这里，我们介绍了一种基于对称石墨烯的结构，其中包含六角形硼化硼（HBN）层，其中已将两个非线性层用作覆盖层来改善混合表面拼音子播种机 - 帕拉斯蒙 - 果皮的限制。得出了一个新的分析模型。一组非线性方程是通过数值求解的，并报告了获得的结果。将非线性培养基与混合石墨烯-HBN层一起利用，可以通过更改化学势，松弛时间和非线性因子来调整结构的传播特性。这项研究是针对两个频率区域进行的：上层静脉和下部静止带。数值结果表明，以45 thz的频率以hsp3在上层静止的频带中传播的Hsp3的长长（LPROP =300μm）和大量的绩效（FOM = 98）。提出的结构及其分析模型可以为中红外等离子体学的可调设备设计提供新的见解。
The hybridization of hyperbolic Polaritonics with THz Plasmonics has attracted immense attention due to its fascinating applications in this region. However, to effectively enhance the performance of these coupled modes, one way is the usage of smart materials in the heterostructures. Here, we introduce a symmetric graphene-based structure containing hexagonal Boron Nitride (hBN) layers, where two nonlinear layers have been utilized as claddings to improve the confinement of Hybrid Surface Phonon-Plasmon-Polaritons. A new analytical model is derived. A set of nonlinear equations are solved numerically and the obtained results are reported. Harnessing a nonlinear medium together with hybrid graphene-hBN layers allows one to tune the propagation properties of the structure by changing the chemical potential, the relaxation time, and the nonlinear factor. The study has been done for two frequency regions: the upper Reststrahlen and the lower Reststrahlen bands. The numerical results show a long propagation length (Lprop=300 μm) and a large Figure of Merit (FOM=98) for HSP3 propagating in the upper Reststrahlen band at the frequency of 45 THz. The proposed structure and its analytical model can open new insight into the design of tunable devices in mid-infrared plasmonics.
