Abstract ：
Metamaterials (MMs) have become increasingly prominent in terahertz flexible devices. However, bending deformation often alters the structure of the unit, which affects the response performance and stability of MMs. Here, a metal-aperture metamaterial (MA-MM) utilizing the strong coupling effect induced by two resonance modes is innovatively proposed to address the mentioned limitations. Specifically, it is found that the coupling state between multiple resonance modes remains consistent at different bending angles. Under these circumstances, the generated Rabi splitting peak presents stable response performance even under low resonance intensity caused by excessive deformation. The experimental results demonstrate that despite the amplitude of two resonant peaks decreasing significantly by 87.6%, the Q-factor of the Rabi splitting only reduced by 14.8%. Furthermore, armed with the response mode of the Rabi splitting being unaffected by plasma excitation range, the designed MA-MMs are able to maintain constant Q-factors and frequencies on curved surfaces of varying sizes. These findings exhibit the characteristics of electromagnetic response for multi-mode resonance-coupled MAMMs on different curved surfaces, presenting a novel design approach for terahertz flexible functional devices.

Abstract ：
Constructing abundant interfaces in composite catalysts to promote their synergistic effects is the key, though a tough challenge for enhancing photo-Fenton catalysts performance. Herein, a pore-confinement strategy is proposed to construct plasmonic Z-scheme PGDY@MIL(Fe/Cu) for ultra-fast removal dinotefuran. Graphdiyne was grown on Cu sites of MIL(Fe/Cu) and formed nano-elliptical graphdiyne (PGDY) nanosheets within the confinement of pores, while the C-Cu interfacial channels were constructed to promote electron transfer in the catalytic process. Upon illumination, PGDY strongly coupled with the incident light and localized surface plasmon resonance (LSPR) could be excited, thus enhancing light absorption efficiency of PGDY@MIL(Fe/Cu) at 375–600 nm and inducing numerous hot electrons. These unique properties accelerated separation efficiency of PGDY@MIL(Fe/Cu) for photogenerated carriers, which boosted the generation rate of active radicals and Fe3+/Fe2+ and Cu2+/Cu+ cycling rates during photo-Fenton catalysis. Finally, PGDY@MIL(Fe/Cu) exhibited excellent catalytic degradation kinetics (99.1 % within 40 min), mineralization efficiency (98 % within 2 h), and catalytic cycling stability for dinotefuran (DNT) compared to the reported advanced catalyst. © 2024

Abstract ：
Electromagnetic metamaterials feature the capability of squeezing photons into hotspot regions of high intensity near-field enhancement for strong light-matter interaction, underpinning the next generation of emerging biosensors. However, randomly dispersed biomolecules around the hotspots lead to weak interactions. Here, we demonstrate an all-silicon dielectric terahertz metamaterial sensor design capable of passively trapping biomoleculars into the resonant cavities confined with powerful electric field. Specifically, multiple controllable high-quality factor resonances driven by bound states in the continuum (BIC) are realized by employing longitudinal symmetry breaking. The dielectric metamaterial sensor with nearly 15.2 experimental figure-of-merit enabling qualitative and quantitative identification of different amino acids by delivering biomolecules to the hotspots for strong light-matter interactions. It is envisioned that the presented strategy will enlighten highperformance meta-sensors design from microwaves to visible frequencies, and serve as a potential platform for microfluidic sensing, biomolecular capture, and sorting devices.

Abstract ：
The planar hybrid metallic microstructured metamaterials can utilize the transverse electromagnetic resonance coupling effect of adjacent resonant units to enhance the absorption bandwidth (ABW), which is widely used in the design of broadband terahertz (THz) absorbers. However, it is difficult to further broaden the ABW since only a limited number of resonant units can be arranged in the 2-D plane. Here, we propose a pyramidal 3-D metamaterial absorber that increases the number of resonances by superimposing metallic dielectric layers with different sizes in the vertical direction. Ultrawideband wave absorption at THz frequencies is realized by longitudinal electromagnetic resonance coupling between the layers of the metamaterial structure. The results show that the 3-D metamaterial achieves more than 90% ultrabroadband absorption in the range of 0.83-2.73 THz with the relative ABW exceeding 106%. In addition, the equivalent circuit model of the absorber is constructed to verify the simulation results. This study provides a novel idea for the design and processing of ultrawideband THz absorbers.

Abstract ：
Terahertz metamaterial absorbers (TMAs) have exhibited significant potential in high-speed communication, sensing, and imaging, attributed to their thin thickness and excellent wave-absorbing capabilities. However, traditional sandwich-structured metamaterial (MM) absorbers lack the tunable absorption performance once fabricated, severely limiting their applications. In this article, we propose a tunable TMA by integrating liquid crystal (LC) within the MM as a dielectric layer. By applying a bias electric field, the refractive index of the LC can be changed, thereby achieving the tunable resonant frequency. Particularly, the dual-band absorption and polarization insensitivity is accomplished through a symmetrical porous mesh structure, which can induce double magnetic dipole resonance modes, and this expands the tunable frequency range of the absorber. Simulation results show that the two resonant frequencies can be continuously tuned from 0.266 to 0.294 THz and from 0.358 to 0.394 THz, with a tunability of 9.5% and 9.1%, respectively. This novel design provides an effective method for developing tunable TMAs, holding great significance in advancing the performance of terahertz (THz) devices.

Abstract ：
Terahertz (THz) metasurfaces have garnered significant interest in biochemical sensing due to their ability to confine field energy in deep subwavelength areas, dramatically enhancing the light-matter interaction. However, the substrate effect prevalent in conventional metasurfaces prevent the enhanced field penetrating into the substrate from interacting with matter, thereby severely limiting the sensitivity. Here, a 1-D V-shaped THz metasurface using a high refractive index HR-Si prism as an external coupler is reported. Tightly confined spoof surface plasmon polariton (SSPP) modes are excited on its all-metallic surface for strong light-matter interactions. The electric field is highly confined within the V-shaped resonant cavity, without any negative effects from the substrate. Owing to this, the metasurface exhibits outstanding performance in the sensing process with a sensitivity of 0.45 THz/RIU, a quality (Q) factor of 140.1, and a figure of merit (FoM) of 54.9 RIU-1. Crucially, the dynamic modulation of plasmon modes allows for a close match with molecular vibrations, enhancing the characteristic absorption of L-histidine by 33.34-fold. This integrated sensor with metasurfaces and prisms shows great potential for the THz detection of trace molecules.

Abstract ：
Metamaterials based on quasi-bound states in the continuum (qBICs) with manipulable resonance quality (Q) factors have provided a standout platform for cutting-edge terahertz (THz) sensing applications. However, most so far have been implemented as conventional metal patch structures with adjacent substrate layers, incurring the limitation of insufficient light-matter interaction due to substrate effects. Here, qBIC-driven metamaterials with substrate-free metallic aperture structures for tailoring light-matter interactions and exhibiting near-ideal sensing performance is introduced. Specifically, it is incorporated ultrafast femtosecond laser processing technology to fabricate H-type metallic aperture metamaterials with accessible high-contrast Q factor resonances allowed by in-plane symmetry breaking. Correspondingly, stronger light field energies are applied to the interactions due to completely eliminating the confinement of the substrate effect, enabling experimental sensitivity of up to 0.86 THz RIU-1 for the qBIC resonance, 1.9 times that of the conventional dipole resonance. Moreover, a high Q qBIC resonance achieved by optimized asymmetry parameter is exploited for detecting ultrathin layers of L-proline molecules as low as 0.87 nmol. It is envisioned that this approach will deliver insights for real-time, precise, and high-performance detection of trace biomolecules, and open new perspectives for realizing ideal performance metadevices. A BIC-driven substrate-free terahertz metamaterial sensor is developed to completely overcome the limitation of insufficient light-matter interaction due to substrate effects. The experimental results report a sensing sensitivity up to 0.86 THz RIU-1 and exploit the tunable characteristic of the qBIC resonance to customize the structural configuration for different detection scenarios. image

Abstract ：
By resolving specific absorption peaks of biochemical molecules in the terahertz region, terahertz spectroscopy demonstrates potential for broad applications in biomedicine and environmental monitoring. However, to achieve wide-frequency-range detection of analytes, it is often necessary to deploy numerous parametermultiplexed metasurfaces with varying unit cell geometries. This increases both the initial preparation steps and the sensor size, thereby limiting the full potential of terahertz technology in the practical analysis of trace molecules. Here, we propose an innovative distance-multiplexed fingerprint sensor based on a metal-dielectric grating composite structure. By utilizing the localized surface plasmon polartions (LSPPs) mode excited by the top metal metamaterial, the electric field is confined within the narrow gap between the metal and the dielectric grating. It is found that the local electric field and resonant frequency are highly sensitive to spacing variations. By controlling the distance between the metal and dielectric grating using a distance multiplexing strategy, the electric field distribution is adjusted, resulting in resonance peaks that span a wide terahertz frequency band, thereby significantly enhancing the molecular fingerprint broadband signal. The results show that compared with the sensing method detected on metal substrate, the maximum enhancement of the sensor is up to 70 times, and the absorbance enhancement factor of 0.47 THz to 0.56 THz is greater than 12.3 dB. Our research is expected to provide a flexible method for detecting trace chemical substances and biomedical samples in the broadband terahertz spectral region.

Abstract ：
Metallic resonators allow the manipulation of electromagnetic fields in subwavelength volumes for strong lightmatter interaction, underpinning emerging flat-optics devices. Metamaterials designed with optimized effective mode volume (Veff) for stimulating and maximizing the utilization of high-density photons are highly desirable for sensing applications. Here, we demonstrate a bowtie-type terahertz (THz) metallic aperture metamaterial structure with low Veff for enhanced biosensing. The device leverages the inherent characteristic of the femtosecond laser fabrication process enabling wedge cavities down to 3 mu m by tailoring the pulse energy, whose sensing performance is superior to trapezoidal ones. Such a substrate-free, microcavity metallic metamaterial sensor with extremely strong interactions achieves an experimentally normalized sensitivity of 0.654 RIU-1, and demonstrates the detection of L-proline down to 0.87 nmol. These findings provide new insights into the design and optimization of efficient THz metamaterials with tightly confined fields for ultrasensitive biomolecular detection.
