Topic Information

Dear Colleagues,

Metamaterials are a recent development in electromagnetics that have immense potential applications. Metamaterial absorbers are a class of metamaterial structures that can absorb all incident electromagnetic radiation. Terahertz metamaterial absorbers operate in the terahertz band. The terahertz band is not as thoroughly explored as the microwave and the optical bands—a gap infamously known as the “terahertz gap”. However, many researchers are contributing to this domain, and these absorbers can also be used for sensing applications, such as refractive index sensing, analyte depth sensing, biomedical sensing, food quality sensing, gas detection, etc. The development of highly sensitive polarization- and incident-angle-independent designs is still a challenging topic of research.

A frequency magnetically tunable perfect absorber based on graphene in the terahertz (THz) region is proposed. The performance is analysed using the 4 × 4 transfer matrix method, demonstrating that the perfect absorption frequency of the proposed absorber for a left-handed circularly polarized (LCP) wave can be dynamically tuned by varying the external static bias magnetic field in three frequency ranges (0.95–2.2 THz, 4.15–5.4 THz, and 7.3–8.55 THz). Due to the destructive interference of the reflected waves and the graphene-induced photonic band gap, the maximum absorption of the LCP wave can reach 99.91%. In addition, the proposed absorber can tolerate a wide range of incident angles for the LCP wave. This study may have great potential for various applications, such as detectors, sensors, and other optoelectronic devices in the THz region. Full article
