摘要：
扭角电子学（Twistronics）最初在电子学领域提出，旨在通过堆叠二维材料之间的扭转角来调控电子性质，为材料科学提供了一种开创性的方法。将这一概念扩展到光子学，尤其是利用超表面，为在亚波长尺度上操控宽电磁频谱中的光提供了有前景的途径。然而，扭角电子学在光子学领域所呈现的可能性仍远未被充分发掘。在本工作中，我们研究了一种由双层线型超表面组成、工作于微波频段的光子构型，其中层间扭转角控制系统行为。我们的研究结果表明，这种操控显著改变了结构的电磁响应，带来了增强的共振、可调谐性和模式耦合。这种由扭转诱导的调制导致共振向低频范围移动，从而有效缩小了结构的电尺寸。我们的研究证明了将扭角电子学集成到光子设计中的可行性，并为开发可调谐和可重构光子器件开辟了新途径。
英文摘要：
Twistronics, originally conceptualized within the electronics domain to modulate electronic properties through the twist angle between stacked two-dimensional (2D) materials, presents a groundbreaking approach in material science. This concept's extension to photonics, especially using metasurfaces, offers a promising avenue for manipulating light at subwavelength scales across a broad electromagnetic spectrum. Nevertheless, the possibilities that twistronics presents within the realm of photonics are still significantly untapped. In this work, we explore a photonic configuration consisting of a dual-layer wire metasurface operating within the microwave frequency spectrum, where the interlayer twist angle governs the system. Our findings reveal that such manipulation significantly alters the electromagnetic response of the structure, leading to enhanced resonances, tunability, and mode coupling. This twist-induced modulation results in a resonance shift towards the low-frequency range, effectively miniaturizing the structure's electrical dimension. Our study demonstrates the feasibility of integrating twistronics into photonic designs and opens new pathways for developing tunable and reconfigurable photonic devices.
