Summary: This study proposes a flexible all-dielectric metamaterial by embedding zirconia microspheres into a vanadium dioxide/polydimethylsiloxane composite, allowing for thermal and mechanical tuning of THz wave transmission. The metamaterial exhibits tunability of the 1st and 2nd order magnetic resonances at specific frequencies through temperature changes and stretching. This all-dielectric metamaterial provides a promising alternative for developing actively tunable, flexible, and versatile THz devices.

Summary: The article introduces the use of THz plasmonics and subwavelength scale artificial structures to detect residual herbicides/pesticides. Experimental results show that the THz MMA platform can detect herbicides/pesticides down to 5 ppm. This suggests that the THz MMA platform could be an important method for highly sensitive THz applications.

Summary: This study investigates the use of vanadium dioxide (VO2) as a metamaterial surface or coupled with a metallic metamaterial surface in terahertz frequency range. The VO2 thin films were patterned into a unique geometry and compared with gold (Au) patterns to evaluate their performance as tunable THz filters. The results show that VO2 exhibits controllable metamaterial properties, while Au-based structures show resonant transmittance modulation with temperature changes.

Summary: This research presents the design and analysis of a high-quality factor (Q) dielectric metamaterial sensor (DMMS) for biosensing applications. The sensor consists of a silicon-based dielectric resonator, a graphene ring, a silicon dioxide (SiO2) substrate, and a gold metallic layer. The proposed sensor exhibits perfect absorption at a frequency of 4.06 THz with an absorption rate of 99.993%. It has the unique features of ultra-thin structure, simple design, tunability, polarization insensitivity, ultra-narrow absorption bandwidth (BW), high sensitivity, high figure of merit (FOM), and very high quality factor (Q), making it suitable for detection of dengue, malaria, and glucose.

Summary: The proposed all-metal titanium pyramid structured metamaterial absorber (MMA) achieves broadband absorption, efficient solar-selective absorption, and high photothermal conversion efficiency. The MMA exhibits strong and broadband absorption due to LSPP absorption, coupled effects of multiple plasmons, and high loss of the titanium material. It also shows wide-angle incidence and polarization insensitivity, with great processing accuracy tolerance.

Summary: In this paper, the potential of using a graphene-based hyperbolic metamaterial as a tunable optical power limiter and/or controllable laser noise suppressor for the terahertz frequency range is investigated. This is the first demonstration of such functionalities achieved with a voltage-controlled nonlinear hyperbolic metamaterial using graphene. The authors believe that these structures, achievable through planar deposition techniques, will have practical applications in THz systems that require optical power limiting.

Summary: Josephson junctions serve as high-sensitivity magnetometers and voltage amplifiers, and are crucial for high-performance cryogenic and superconducting quantum computers. Despite the potential degradation in device performance caused by quasiparticle generation, this phenomenon also offers opportunities for detecting electromagnetic radiation with sensitivity.Detection of single photons in near-infrared range has been demonstrated by coupling photons to the localized surface plasmons of a graphene-based Josephson junction, revealing the critical role of quasiparticles in the detection mechanism.
