论文摘要
由于涉及漏水的波浪机制，由于其高频选择性和梁扫描功能，因此非常有希望的准分子（QO）组件的候选阵列。我们在这里展示如何通过打破某些单位电池和晶格对称性，可以实现与沿阵列表面泄漏波散分散体相关的丰富的透射共振系列。通过将计算矩（MOM）计算的2-D和1-D周期方法与Qo Terahertz（THZ）时间域测量结果相结合，我们提供了物理见解，数值和实验证明与非凡透射峰相关的不同机制以及与插槽数量演变有关的不同机制。多亏了使用的THZ仪器，我们还能够探索所涉及的不同频率组件的时间依赖性发射。
Extraordinarily transmitting arrays are promising candidates for quasi-optical (QO) components due to their high frequency selectivity and beam scanning capabilities owing to the leaky-wave mechanism involved. We show here how by breaking certain unit cell and lattice symmetries, one can achieve a rich family of transmission resonances associated with the leaky-wave dispersion along the surface of the array. By combining 2-D and 1-D periodic method of moments (MoM) calculations with QO terahertz (THz) time-domain measurements, we provide physical insights, numerical, and experimental demonstration of the different mechanisms involved in the resonances associated with the extraordinary transmission peaks and how these evolve with the number of slots. Thanks to the THz instrument used, we are also able to explore the time-dependent emission of the different frequency components involved.
