How researchers created metasurfaces for THz signal distribution that don't have the typical drawbacks of similar structures. How the tile arrays are laid out to form the metasurface. What do the meta ...
Terahertz (THz) radiation occupies the spectral gap between microwave and infrared frequencies, typically defined as 0.1–10 THz. Its unique position enables non-ionising probing of molecular ...
Fig. 1 THz wave generation from MoS2 through quantum interference. (a) Schematic diagram of THz wave generation from MoS2 under two-color light excitation at normal incidence. (b) THz waveforms ...
Schematic of chiral terahertz generation and control: A femtosecond laser interacts with a patterned spintronic emitter, producing elliptically or circularly polarized terahertz waves. Rotating the ...
A simple tweak to the usual setup is all that is needed to enhance a spectroscopy technique that uses terahertz wavelengths to probe samples, physicists at RIKEN University, WakaÌ…, Japan, have ...
A chip-sized device that can switch between two topologically protected light structures opens up a route to wireless ...
Sixth-generation, or 6G, cellular networks are the next step in wireless communication, and electromagnetic terahertz waves are seen as crucial to its development. However, terahertz waves, with their ...
Terahertz waves are becoming more important in science and technology. But generating these waves is still a challenge. A team has now developed a germanium component that generates short terahertz ...
