Here’s the clever bit. If you tighten the handle by screwing it fully in, it rotates the necessary element for circular polarization. Loosen the handle by unscrewing it, and it adjusts the ...

The conventional terminology for that case however is not the word “rotary”, it is the word “circular”. We thus speak of vertical polarization, horizontal polarization, and circular polarization. What ...

They propose a cross-shaped microstructure metamaterial for achieving cross-polarization conversion and linear-to-circular polarization conversion in the terahertz frequency range. The study ...

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

A new instrument can measure circular polarization, caused by the biosignature homochirality, from a rapidly moving helicopter: expanding possibilities in the search for life in space. When the latest ...

In this study, the researchers demonstrated that the valley polarization of IXs can be effectively controlled by adjusting the twist angle. Both the degree of circular polarization (DCP ...
