“…In 2021, Angana Bhattacharya et al based on similarity theory, designed a MM with a toroidal split ring resonator flanked by two asymmetric C resonators to realize a dual-EIT [13] . Combining the metallic structure with graphene, Deng et al achieve to manipulate the single MIT windows in 2021 [14] and realize to control the dual-MIT windows in 2023 [15] . According to the previous reports, most designs achieved an alteration in the strength of the dual-EIT effect by varying the distance between the metastructures in MMs.…”

Metamaterial induced transparency (MIT) has shown great application potential in terahertz regime, which is of great significance in constructing photonic components such as slow light systems and tunable filters. The single or multiple transparent windows can be induced through near-field coupling via two or more resonant modes. Compared with the single MIT, multi-MIT effect can realize multiband sensing, communication, and storage applications. Here, we design a dual-MIT metastructure composed of three bright resonators including a cut-wire resonator (CWR), a pair of large toroidal split ring resonators (LTSRRs), and a pair of small toroidal split ring resonators (STSRRs). Dual-MIT windows can be induced through coupling between the electric dipole resonance and two inductance capacitance (LC) resonances. By optimizing and adjusting the geometric parameters of the metasurface, the resonant strength could be suppressed or enhanced. Thus, we can passively manipulate the frequency and amplitude of the dual-MIT windows and realize the switching between the two windows and single MIT. In addition, by actively tuning the conductivity of photosensitive Si introduced in the gap of the LTSRRs and STSRRs, we observe the LC resonance can be weakened to quench the dual-MIT windows. Our research provides an approach to explore the miniaturized, multi-functional, and switching components in terahertz regime.

Graphene‐based terahertz (THz) devices have emerged as promising platforms for a variety of applications, leveraging graphene's unique optoelectronic properties. This review explores recent advancements in utilizing graphene in THz technology, focusing on two main aspects: THz molecular sensing and THz wave modulation. In molecular sensing, the environment‐sensitive THz transmission and emission properties of graphene are utilized for enabling molecular adsorption detection and biomolecular sensing. This capability holds significant potential, from the detection of pesticides to DNA at high sensitivity and selectivity. In THz wave modulation, crucial for next‐generation wireless communication systems, graphene demonstrates remarkable potential in absorption modulation when gated. Novel device structures, spectroscopic systems, and metasurface architectures have enabled enhanced absorption and wave modulation. Furthermore, techniques such as spatial phase modulation and polarization manipulation have been explored. From sensing to communication, graphene‐based THz devices present a wide array of opportunities for future research and development. Finally, advancements in sensing techniques not only enhance biomolecular analysis but also contribute to optimizing graphene's properties for communication by enabling efficient modulation of electromagnetic waves. Conversely, developments in communication strategies inform and enhance sensing capabilities, establishing a mutually beneficial relationship.
