Air superiority doesn’t come for free — it has to be seized, often at great cost, from an adversary determined to deny it.

Traditionally difficult to access, the terahertz (THz) region of the electromagnetic spectrum (0.1–10 THz), is higher in frequency than most electronic sources and lower in frequency than most optical ...

There are parts of the universe that are extremely hard to see, even for our most advanced telescopes. Gas and dust don't ...

Princeton University researchers have found a way to extend the near-field range for sub-terahertz wireless systems using off ...

O, developed by researchers at Science Tokyo enables efficient ammonia synthesis under mild conditions while overcoming the ...

K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually ...

Abstract: This paper proposes an artificial neural network (ANN)-based synthesis method for nonuniform linear arrays with mutual coupling effects. The proposed method can simultaneously optimize the ...
