(Nanowerk News) Chip-scale silicon photonics optical phased array (OPA) is widely used in free-space communication. However, due to the limitation of optical device design and manufacture, the ...

Phased array technology is far from new. Phased-array antennas have been used for decades in a variety of military applications. Now, however, their use in 5G systems in the Band 2 frequency range is ...

In this paper, the authors present an efficient Artificial Neural Network (ANN)-based model to estimate both azimuth and elevation arrival angles of a signal source. To achieve this goal, the ANN ...

POLARIZATION. We use the word in everyday speech to mean a division into two groups with sharply contrasting opinions or beliefs. But the word has another use in physics and electrical engineering to ...
