Terahertz (THz) waves, which are located between microwaves and infrared light in the electromagnetic spectrum, can pass through many materials without causing damage, making them useful for security ...

You may not realize it, but the Doppler effect is everywhere in our lives, from tracking the speed of cars with radar to locating satellites in the sky. It's all about how waves change their frequency ...

Researchers from Beihang University in China have developed a spintronic THz emitter featuring a microscale stripe pattern that enables the modulation of chirality during THz wave generation. This ...

(Nanowerk Spotlight) The development of compact and efficient terahertz radiation sources is crucial for the advancement of terahertz technology across a range of applications from imaging and sensing ...

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 ...
