Notably, circularly polarized waves were used as excitation sources to intrinsically induce rotational electron movement along the elliptical arcs, effectively simulating orientation 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 ...

A revolutionary new spintronic device developed in China enables powerful, precise control of terahertz (THz) wave ...

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

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

It is shown in this paper that a null-free radiation pattern must contain all axial ratios (ratio of semiminor to semimajor axes) of elliptical polarization ranging from -1 (circular polarization of ...
