In the early 1980s, researchers at NASA's Jet Propulsion Laboratory in California realized that stable reference signals generated by a hydrogen maser atomic clock could be distributed over optical ...

Abstract: We show that state-of-the-art phase noise and high frequency stability could be simultaneously achieved in a microwave oscillator based on the sapphire-loaded cavity resonator. Two 9 GHz ...

Abstract: Intelligent reflecting surface (IRS) is an enabling technology to engineer the radio signal propagation in wireless networks. By smartly tuning the signal reflection via a large number of ...

Chaos is the study of the underlying determinism in the seemingly random phenomena that occur all around us. One of the best experimental demonstrations of chaos occurs in electrical circuits when the ...
