Abstract: This article presents an innovative wireless power and drive transfer (WPDT) system with inherent modulation and demodulation functionality. For high-frequency alternating input voltage, ...

The moment a cyberattack strikes, the clock starts ticking. Files lock up, systems stall, phones light up and the pressure skyrockets. Every second counts. What happens next can mean the difference ...

In a digital world, why bother with analog? Well, sometimes it can still be the right solution. Take, for instance, the analog multiplier (see figure). At its simplest, it’s a circuit that leverages ...

Communicating with someone thousands of miles away is now just a few keystrokes away, thanks to the internet and other forms of communication. Modern communication leverages a variety of wired and ...

What is a Digital Signal Processor? A digital signal processor (DSP) is a microprocessor chip specially designed to meet the practical needs of digital signal processing. DSPs are fabricated on MOS ...

Oscillators ensure frequency stability in communication devices by generating precise reference signals, reducing drift, and enabling syncronization, modulation, and clarity. Oscillators are circuits ...

Commercial deployment of 6G communications systems is still not expected until the end of the decade, yet NTT Docomo has already been at the forefront of a string of developments moving towards the ...

A novel side-channel attack dubbed "RAMBO" (Radiation of Air-gapped Memory Bus for Offense) generates electromagnetic radiation from a device's RAM to send data from air-gapped computers. Air-gapped ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240045, discusses complete-basis-reprogrammable coding metasurface for generating dynamically-controlled holograms under ...
