Terahertz metamaterials wave separator
2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz), 2021A miniaturized terahertz (THz) metamaterials wave separator with the structure of four uniform units in z direction is proposed. The unit has three layers of gold (Au)-silicon dioxide (SiO 2 )-polymethacrylimide (PMA) from up to down. Perfect steep cut-off has been achieved, and the transmittance of the device is reduced from 80% to 5% within 0.06THz ...

Multiband terahertz metamaterial absorber
Chinese Physics B, 2011This paper reports the design of a multiband metamaterial (MM) absorber in the terahertz region. Theoretical and simulated results show that the absorber has four distinct and strong absorption points at 1.69, 2.76, 3.41 and 5.06 THz, which are consistent with 'fingerprints' of some explosive materials.

Novel Terahertz Electric Metamaterials
Optical Terahertz Science and Technology, 2007Planar electric metamaterials and their inverse structures are demonstrated to show complementary electrical resonant behavior in terahertz time-domain spectroscopy. Simulations and measured data agree well and illustrate potential applicability of these materials for terahertz devices.
