Atmospheric optics is a branch of optics and photonics that studies how light behaves in the Earth ... effects involving sunlight and the propagation and distortion of electromagnetic signals ...

Controlling asymmetric light propagation—where light preferentially travels in one direction while being blocked or scattered in the opposite direction—has been a longstanding need in optical ...

The Department of Atmospheric Propagation and Effects deals with laser applications in the free atmosphere. The focus here is on applications of laser radiation over long distances, such as optical ...

Their study revealed that coherence entropy remains stable during the propagation ... operate through atmospheric turbulence, to advancing imaging technologies that rely on light fields traveling ...

There are several important factors which affect the propagation of sound: geometric spreading, atmospheric effects, and surface effects. These are discussed separately below. Attenuation from a point ...

“The ionosphere contains charged particles, such as ions and electrons, and when subject to turbulence they affect the propagation of radio ... caused by optical effects that atmospheric disturbances ...
