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 ...

Humans typically blink 4 times per second, equivalent to a frequency of 4 Hz. Blinking at a rate of 1 billion times per second, or 1 GHz, is not possible for a human being. But this is the current ...

Researchers have discovered a groundbreaking use of terahertz (THz) imaging to visualize cochlear structures in mice, offering non-invasive, high-resolution diagnostics. By creating 3D ...

A spintronic THz emitter with a microscale stripe pattern enables room-temperature polarization control, enhancing THz applications in wireless communication and biomedical imaging.

Schematic of chiral terahertz generation and control: A femtosecond laser interacts with a patterned spintronic emitter, producing elliptically or circularly polarized terahertz waves. Rotating ...
