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 ...

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 ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2023.220148 discusses the direct field-to-pattern monolithic design of holographic metasurface via residual encoder-decoder convolutional ...

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 ...

Microwave antennas used for communications systems such as wireless local area networks. The antennas operate at frequencies up to 60 GHz at distances of 2 km to 3 km. Find a way to test microwave ...
