Amplitude modulation (AM) was first introduced to enable long-range wireless audio communication, representing a major advancement over wireless telegraphy using spark-gap transmitters. Understanding ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240250, discusses on-chip multi-channel near-far field terahertz vortices with parity breaking and active modulation. Vortex ...

Donchian channels can help you identify trends and breakout signals, but period length, market conditions, risk, and their relevance to other indicators must be considered.

By Victor Moroz and Shela Aboud The transition from finFET technology to Gate-All-Around (GAA) technology helps to reduce transistor variability and resume channel length scaling. It also brings ...

A new technical paper titled “Large-scale sub-5-nm vertical transistors by van der Waals integration” was published by researchers at Hunan University. “ Here, we demonstrate a layer-by-layer transfer ...

A closed-form formula for the nonlinear interference (NLI) estimation using the Gaussian noise (GN) model in the presence of inter-channel stimulated Raman scattering (ISRS) is derived. The formula ...
