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

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

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 ...

Polarization density (also known as “electric polarization,” or simply just “polarization”) decides the response of an object towards an electric field. It is also responsible for the ...

At face value, the treadmill and the elliptical seem like two pretty similar pieces of gym equipment. Both machines have you up on your feet, moving in the same plane of motion and largely calling ...
