This work demonstrates the magnetic field-induced spectral properties of metamaterials incorporating both indium antimonide (InSb) and tungsten (W) in the terahertz (THz) frequency regime. Nanostructure materials, layer thicknesses and surface grating fill factors are modified, impacting light-matter ...
Simply put, bulk electrons assist the surface-state electrons by sinking electronic heat. The maximum output power for the terahertz third-harmonic—i.e., radiation with three times the same energy—was accomplished in a metamaterial that comprised a topological insulator film along with a metallic...

Low insertion-loss single-layer and bilayer metamaterial filters in terahertz (THz) frequency regime were demonstrated on top of low cost flexible Scotch tape by utilizing pattern transfer method. The transmittance of the flexible 51-μm-thick Scotch tape was found out to be higher than 0.85 in...
We experimentally demonstrate, for the first time, an optically implemented blueshift tunable metamaterial in the terahertz (THz) regime. The design implies two potential resonance states, and the photoconductive semiconductor (silicon) settled in the critical region plays the role of intermediary for ...
Flexible chiral metamaterials in the terahertz regime: a comparative study of various designs Five different chiral metamaterials in the terahertz (THz) regime, fabricated on fully flexible polyimide substrates, are comparatively studied via numeric...

Terahertz metamaterials are designed to interact at terahertz (THz) frequencies, which is usually defined as 0.1–10 THz. Terahertz regime is located at the interface of electronics and photonics where technologies directly translated from microwave and.
These materials are reviewed, with emphasis on metamaterials for engineering of terahertz waves, from the regime of passive devices to broader areas in which functionalized active terahertz devices are particularly required.doi:10.1002/adma.202000250Seojoo Lee...
Artificial material designs can operate at frequencies from megahertz through terahertz, where there are numerous communication and imaging applications. For example, lens antennas could benefit both by a reduction in aberrations, which translates directly into increased gain, and by a reduction of mass...
