An electromagnetic wave or signal traveling from “here” to “there” has an electrostatic field component that we call its E-field and whose direction we assign as the signal’s polarity. Often, the ...

The circular polarization of light that planets reflect is often neglected because it is very small compared to the linear polarization. It could, however, provide information on a planet’s atmosphere ...

Fast radio bursts (FRBs) are a kind of energetic cosmic radio burst. Though their duration is usually at millisecond scale, their energy (estimated isotropically) reaches 10 ^36 ～10 ^41 erg, ...

a, Device structure of an on-chip infrared circular polarization detector based on the metal-MoS2-metal architecture. b, Band diagram of the two metal-MoS2 junctions functioning as two Schottky diodes ...

The polarity of a supermassive black hole lurking at the center of M87, a galaxy 55 million light-years from Earth, ...

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 ...

"Studying the relic radiation from the beginning of the universe is critical for understanding how the entire cosmos came to be and why it is the way it is." When you purchase through links on our ...
