摘要

我们利用基于有限元方法的模拟,研究了太赫兹波在星号形纳米槽天线中的电场约束。星号槽天线由一个单槽和一个 X 形槽天线组成,其近场和远场特性取决于耦合角。在耦合角较小的情况下,X 形和耦合槽天线实现了太赫兹波的三维限制。考虑到槽形天线的间隙大小,我们从局部场强和聚焦度的角度分析了与耦合角相关的约束性能。这些发现为研究太赫兹频率体系中的光物质相互作用提供了宝贵的设计见解。

In-depth study for confinement of electromagnetic wave in a coupled terahertz nano-slot antenna

In-depth study for confinement of electromagnetic wave in a coupled terahertz nano-slot antenna

We study the electric-field confinement of terahertz waves in an asterisk-shaped nano-slot antenna using finite-element-method-based simulations. The asterisk slot antenna, consisting of a single slot and an X-shaped slot antenna, exhibits near- and far-field characteristics depending on the coupling angle. In a regime of small coupling angles, three-dimensional confinement of terahertz waves is realized in X-shaped and coupled slot antennas. We analyze the coupling-angle-dependent confinement performance in terms of localized field strength and focusing degree, considering the gap size of the slot antennas. These findings provide valuable design insights for studying light-matter interactions in the terahertz frequency regime.
