Realization of a multi-band terahertz metamaterial absorber using two identical split rings having opposite opening directions connected by a rectangular patch

Ben-Xin Wang et al.

Summary: This paper demonstrates a multi-band metamaterial absorber in the terahertz regime using a periodically arranged surface structure. The absorber is comprised of a surface structure with two split rings and a rectangular patch, which can generate dual-band absorption peaks through a strong electromagnetic interaction with incident terahertz waves. The dimensions of the surface structure play a key role in controlling and adjusting the resonance performance. Furthermore, optimizing the surface structure can increase the number of absorption peaks.

Miniaturized and Actively Tunable Triple-Band Terahertz Metamaterial Absorber Using an Analogy I-Typed Resonator

Ben-Xin Wang et al.

Summary: This work presents a triple-band terahertz metamaterial absorber with a design focus on miniaturization and compactness. The absorber exhibits near-perfect absorption at three discrete frequency points in the terahertz regime. The absorption peaks are attributed to the localized resonances of an analogy I-shaped resonator, and the response positions of these peaks vary due to the near-field patterns. The study also explores changes in the structure parameters of the resonator and demonstrates polarization-insensitive performance and actively tunable absorption properties by inserting vanadium dioxide.

Imaging Properties of Large Field-of-View Quadratic Metalenses and Their Applications to Fingerprint Detection

Emmanuel Lassalle et al.

Summary: Dielectric metasurfaces are extremely thin nanostructured surfaces that show potential to replace traditional refractive optics such as lenses. Designing large field-of-view metalenses remains a critical challenge, but the use of quadratic phase profiles has been proposed to address this issue. However, there is a trade-off between FOV and optical/detector resolution due to intrinsic distortion in metalenses.
