These results, which surpass current electronic systems by an order of magnitude, have potential applications in radar and high-speed communications. Dense three-dimensional integration of ...

Distributed acoustic sensing detects disturbances in fibre optic signals to identify underwater threats NATO ... essential in safeguarding global communications. Lane Burdette, a research ...

Abstract: To protect underwater acoustic communications from interception, the exchange of encryption keys is necessary. Since underwater devices can be compromised, generating keys on site is a ...

Modern communication networks rely on optical signals to transfer vast amounts of data. But just like a weak radio signal, these optical signals need to be amplified to travel long distances without ...

Abstract: The Internet of Underwater Things (IoUT) is a network of countless connected ... due to limited computational power and battery life. To tackle this, Block Compressed Sampling (BCS) can be ...

We’re not talking WiFi here, but plain optical signals. Free-space optical communication ... beam LEDs or use filtered photo diodes to block ambient noise from sunlight or fluorescent lights.
