我们回顾了本征约瑟夫森结在自发太赫兹电磁波辐射方面的理论和数值研究进展，并报告了我们最近的多尺度模拟方案，以进一步提高辐射功率。从理论上讨论了叠层约瑟夫森结之间的耦合，揭示了孤子激发对大的自发辐射是必不可少的。最后，我们提出了一个实验装置，其中一个本征约瑟夫森结被包围的介质材料，并揭示了辐射功率增强发生调谐介电。
We review theoretical and numerical research developments in intrinsic Josephson junctions in terms of spontaneous THz electromagnetic-wave emission and report our recent multi-scale simulation scheme to further enhance the radiation power. Starting with theoretical treatments on the couplings among the stacked Josephson junctions, we reveal that solitonic excitation is essential for large spontaneous emission. Finally, we propose an experimental setup, in which an intrinsic Josephson junction is enwrapped by the dielectric materials and reveal that radiation power enhancement occurs by tunning the dielectricity.
