Summary: A plasmon-induced terahertz metamaterial absorber is introduced, using a gold bottom layer to block the transmission of terahertz waves, with a topas layer separating the pattern layer and ground layer. The absorber exhibits a 90% absorption bandwidth frequency range of 4.6-7.7 THz, with an average absorption rate of 97.6% in this range. It has polarization insensitivity due to its geometric symmetry, and can maintain over 80% absorption even at an incidence angle of 60 degrees. The absorber also shows good linear frequency shift with refractive index change, with a sensitivity of 1100 GHz per refractive index unit (GHz/RIU), making it suitable for complex electromagnetic scenarios or as a sensing element.

Summary: In this study, a double-open hexagonal ring metamaterial (MM) with high refractive index sensitivity was designed and fabricated to improve the detection sensitivity of terahertz (THz) biosensors. The resonant properties of the MMs were demonstrated through simulations and experiments. The MM sensor showed high sensitivity and low detection limits to glucose and bovine serum protein (BSA) solutions, indicating potential applications in the THz biomedical field.

Summary: The incorporation of nematic liquid crystal in metamaterials enables the tunability of electromagnetic response, with the anisotropic nature of liquid crystal playing a crucial role in influencing the resonant frequency. By carefully designing and infiltrating liquid crystal, the operation frequency of metamaterials can be dynamically modulated, resulting in remarkable red/blue-shift. Recent developments and novel applications of liquid crystal-based metamaterials are also investigated and highlighted.

Summary: A new metamaterial is proposed, which combines the space-coiling concept and multiunit lumped coupling concept, to address the issues of the Helmholtz resonator. This metamaterial exhibits extraordinary acoustic responses related to multiple resonant patterns in the low-frequency regime. It enables acoustic wavefront reshaping, acoustic cloaking, and flexible adjustment of the boundary conditions of inserted obstacles.

Summary: The significant increase in thermal carrier generation rates in MBE-grown p-i-n-i-p GaAs structures is attributed to deactivation of hydrogen-defect/impurity complexes during high-intensity, low-energy electron-beam irradiation. Quantum calculations suggest that deactivation of oxygen impurities is likely the cause of this degradation, with electric-field and excess-carrier-induced dehydrogenation of O-As-H complexes identified as a likely rate-limiting process.
