We present a comprehensive experimental study comparing the propagation characteristics of the virtually unknown TE(1) mode to the well-known TEM mode of the parallel-plate waveguide (PPWG), for THz pulse applications. We demonstrate that it is possible to overcome the undesirable effects caused by the TE(1) mode's inherent low-frequency cutoff, making it a viable THz wave-guiding option, and that for certain applications, the TE(1) mode may even be more desirable than the TEM mode. This study presents a whole new dimension to the THz technological capabilities offered by the PPWG, via the possible use of the TE(1) mode.
我们开展了一项全面的实验研究，针对太赫兹脉冲应用，比较了几乎不为人知的TE(1)模式与平行板波导（PPWG）中广为人知的TEM模式的传播特性。我们证明，有可能克服TE(1)模式固有的低频截止所带来的不良影响，使其成为一种可行的太赫兹波导选择，并且在某些应用中，TE(1)模式甚至可能比TEM模式更具优势。这项研究通过可能使用TE(1)模式，为PPWG所提供的太赫兹技术能力展现了全新的维度。
