Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field ...

Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, ...

Fig. 1. (a) THz optical path diagram based on metasurface. By controlling the phase delays of LCP and RCP waves by unit cells, metasurface can transmit the LCP and RCP components of the incident ...

The composite system of multiple transition metal sulfides was constructed by compounding multiple components, which formed abundant heterogeneous interfaces and polarization sites and promoted ...

Terahertz (THz) waves, which are located between microwaves and infrared light in the electromagnetic spectrum, can pass through many materials without causing damage, making them useful for security ...

Gravitational waves are usually hunted by measuring distance—how space itself stretches and shrinks ever ...
