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 through many materials without causing damage, making them useful for security ...

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

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

The idea was inspired by earlier work involving light that was conducted by Shen Yijie. A co-lead on the new project, Yijie ...

The finest ever map of the cosmic microwave background - the faint evidence of the universe's early form - has yielded ...
