Abstract

We study energy transfer among an array of identical finite-width parallel-plate waveguides in close proximity, via evanescent wave coupling of broadband terahertz waves. We observe stronger coupling with larger plate separations and longer propagation paths. This work establishes a platform to investigate new opportunities for THz components and devices based on evanescent wave coupling.

摘要

我们通过宽带太赫兹波的倏逝波耦合，研究了紧密排列的一系列相同有限宽度平行板波导之间的能量转移。我们观察到，板间距越大、传播路径越长，耦合越强。这项工作建立了一个平台，用于研究基于倏逝波耦合的太赫兹组件和器件的新机遇。
