Mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory is called 'field ...

Mathematicians from the University of Utah have developed a new mathematical theory that could explain how waves and other disturbances in the universe move through materials in varying conditions of ...

In a study of the harsh but beautiful White Sands National Monument in New Mexico, researchers have uncovered a unifying mechanism to explain dune patterns. The new work represents a contribution to ...

An NPA, resembling its radiofrequency counterpart, consists of several typically identical optical antennas. Each antenna emits light of a specific amplitude and phase to form a desired far-field ...
