contents 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.
