A new patterned spintronic emitter enables room-temperature control of terahertz wave polarization.

Called a Cascaded-mode interferometer, it is a single waveguide on a silicon-on-insulator platform that can create multiple ...

Our art reflects a commitment to the pleasant, a subtlety and delay in how we communicate, and an easygoing acceptance of ...

Researchers from Beihang University in China have created a spintronic THz emitter with a microscale stripe pattern that ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

A storm, even once it has passed, can leave traces in the ocean that last for thousands of years. These consist of sediment layers composed of coarse particles, which are different from the finer ...

Terahertz (THz) waves are located between microwaves and infrared light in the electromagnetic spectrum. They can pass ...

Imagine a boxer dodging a punch, a musician perfectly timing a note, or a driver anticipating a green light—the brain can be ...

Directing sound to a specific location is difficult because of how sound waves behave. As vibrations move through the air, ...

A nanoscale modulator has broken the terahertz mark. The ultrafast component efficiently transmits large volumes of data into ...

New audio tech uses ultrasound to create isolated pockets of sound, enabling private listening without headphones.
