Subwavelength confinement of light with plasmonics is promising for nanophotonics and
optoelectronics. However, it is nontrivial to obtain narrow plasmonic resonances due to the …

In recent years, electromagnetic characteristics of metamaterials has aroused great interest
because of innovative fundamental understanding as well as promising potential …

An ultra-sensitive THz metasensor is presented based on quasi-BIC Fano resonance, which
can distinguish extremely dilute concentrations (nM) of solutions. It provides a …

A multi-band metamaterial absorber in the terahertz regime using a periodically arranged
surface structure placed on an ultra-thin insulating dielectric slab backed by a metallic …

In recent years, the concept of bound states in the continuum (BICs) in metasurfaces has
become a research focus, providing an important physical mechanism for engineering high …

A new type of quad-band terahertz metamaterial absorber based on a common sandwich
structure is investigated. In sharp contrast to the most previous studies focused on only …

We experimentally study the effect of near field coupling on the transmission of light in
terahertz metasurfaces. Our results show that tailoring the coupling between the resonators …

Bound states in the continuum (BICs) are widely studied for their ability to confine light,
produce sharp resonances for sensing applications and serve as avenues for lasing action …

A tunable dual‐split‐disk resonator (TDSDR) composed of top and bottom Au split‐disk
resonators (SDRs) in the terahertz (THz) wave is presented. TDSDR exhibits …

Metamaterials that can support ultrasharp resonances using conductively coupled split ring
resonators are potential candidates for designing label-free biomedical sensors. The sharp …
