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

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 ...

Simply rotating the emitter allows for flexible and efficient switching between linear, elliptical, and circular polarization states. Critically, the device maintains high-quality circular ...

The custom design can integrate the following functionalities: superposition of multiple input ports and dichroic beam combination, beam expansion, beam shaping for beams with elliptical cross ...

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

Philippine history is not replete with political polarization. It has only gone to the worst, with the whole world watching. The term "polarization" is used to describe both the division of a society ...
