Abstract

We investigate the electromagnetic modes supported by parallel-plate waveguides created by juxtaposing two planar metasurface junctions, focusing on specific parameter ranges where each junction sustains a line wave. We explore how these waves interact as the waveguide thickness changes, considering both purely reactive and non-Hermitian scenarios (incorporating gain/loss). Our findings suggest the potential to achieve tightly confined, quasi-one-dimensional modes, as well as exceptional points and intriguing transitions between waveguiding and radiative regimes. These findings hold promise for applications in fields ranging from nonlinear optics to sensing and imaging.

平行板元面波导中的耦合线波

摘要我们研究了通过并置两个平面元面结点而形成的平行板波导所支持的电磁模式，重点是每个结点都能维持线波的特定参数范围。我们探讨了这些波如何随着波导厚度的变化而相互作用，同时考虑了纯反应和非赫米提情况（包含增益/损耗）。我们的研究结果表明，我们有可能实现紧密约束的准一维模式，以及波导和辐射状态之间的特殊点和引人入胜的转换。这些发现为非线性光学、传感和成像等领域的应用带来了希望。图表摘要
