Multi-electrode arrays (MEAs) provide a noninvasive interface with sub-millisecond temporal resolution and long-term, ...

Radio over fiber transports RF signals via optical fiber, enabling low-loss distribution for wireless networks, radar systems, and radio astronomy applications.

Photonic computing represents not a radical departure from familiar territory, but rather a natural extension along the electromagnetic spectrum. The transition from gigahertz to hundreds of terahertz ...

Recently, Prof. Andrea Alù from the City University of New York and Dr. Guangwei Hu from Nanyang Technological University in ...

Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...

How a Stanford University research team used acoustic waves to manipulate light. Device implementation involving gold nanoparticles placed in a particle-on-mirror configuration with a compressible ...

Controlling low-frequency broadband sound using compact structures remains a core challenge in acoustics. Achieving efficient, wideband sound absorption with lightweight, thin materials is vital for ...

Abstract: The traction inverters need to operate in asynchronous and square wave modulation, with synchronous modulation suitable for transitioning between them. This article aims to present novel ...
