Design and experimental realization of triple-band electromagnetically induced transparency terahertz metamaterials employing two big-bright modes for sensing applications.

Nanoscale, 2023
Multi-band electromagnetically induced transparency (EIT) effects have attracted widespread attention due to their great application prospects. However, their realization is mainly based on the coupling of multiple sub-resonators that typically exceed ...

Terahertz Metamaterial Absorbers

Advanced Materials Technologies, 2021
AbstractTerahertz metamaterial absorbers (TMAs) can efficiently absorb electromagnetic wave in the range of 0.1–10 THz based on the tunable electromagnetic properties of artificially designed unit cells. TMAs can achieve perfect absorption, as well as broad band absorption.

Reconfigurable Terahertz Metamaterials

Physical Review Letters, 2009
We demonstrate reconfigurable anisotropic metamaterials at terahertz frequencies where artificial "atoms" reorient within unit cells in response to an external stimulus. This is accomplished by fabricating planar arrays of split ring resonators on bimaterial cantilevers designed to bend out of plane in response to a thermal stimulus.

Metamaterial based terahertz detector

2011 International Conference on Infrared, Millimeter, and Terahertz Waves, 2011
We present a metamaterial based terahertz (THz) detector. The detector design, which combines metamaterials and MEMs, is frequency selective, and we have fabricated and tested detectors at 95 GHz and 693 GHz with noise equivalent powers of 1.13 × 10−8 W/√Hz and 2.96 × 10−8 W/√Hz and responsivities of 16,500 V/W and 6,800 V/W, respectively. These values
