So I've been familiar with the basics of polarization since forever, but I recently realized circular polarization is a mystery to me. I've heard of it in conjunction with eg satellite broadcasts, but ...

Left and right circularly polarized light, where the electromagnetic waves spiral in a clockwise and counterclockwise manner as they travel, plays a crucial role in a wide range of applications, from ...

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 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 ...

Images of light patterns captured using the Atom Camera. (Left) Intensity distribution of a microscopic lattice structure generated by a specialized optical device. (Right) Non-trivial polarization ...

A new atom camera uses one ultracold rubidium atom to map light intensity and polarization with spatial resolution below 100 nanometers.

These days, when it comes to GPS devices the antenna is typically part of the package. But what better opportunity for [Pepijn] to learn how to make a GPS antenna from scratch for a badge add-on? A ...
