Vortex beams propagate with inherent orbital angular momentum, which can be harnessed for terahertz manipulation, measurement, and communications. Nonetheless, achieving the high-purity generation of ...

We report on the conversion of an infrared vector beam into THz vortex beams using a ZnTe cubic crystal. We provide a theoretical analysis demonstrating how an infrared vector beam with the azimuthal ...

While relatively weak compared to traditional tornadoes, landspouts can be strong enough to cause damage and warrant caution.
