Summary: In this paper, a dual-band terahertz absorber based on a metamaterial structure is designed, fabricated, and measured. The absorber achieves two absorption peaks at 0.715 and 1.013 THz with high Q-factors of 152.1 and 98.3, respectively, under TE and TM polarized incidence. The prototype of the metamaterial absorber is fabricated using electron beam lithography and electron beam evaporation technology, and its performance is tested using terahertz time-domain spectroscopy. This work offers a new option for designing multi-band terahertz metamaterial absorbers.

Summary: In this article, a novel two-axis optical nano-electromechanical-system (NEMS) accelerometer based on metamaterials is proposed for biomedical applications. The accelerometer utilizes split-ring resonators (SRR) to form a tunable metamaterial device, allowing for sensitive measurement of body accelerations or position estimations. Numerical and analytical analysis of the BioNEMS accelerometer yield functional characteristics such as optical sensitivity, mechanical sensitivity, measurement range, and bandwidth. The results demonstrate that the proposed accelerometer can be used as a highly sensitive nanoscale platform in various medical applications.
