Read our live updates from CES 2026 in Las Vegas to see the latest consumer gadgetry in all of its chatbot-enabled, ...

So if we’re right, each former human is now essentially a radio transmitter and receiver. One plurb sends out a signal that ...

When [Electron Impressions] used a powerful ultrasonic array to project a narrow beam of sound toward a target, he described ...

Spatial control of the phase and amplitude of a laser beam is useful for applications ranging from imaging and holography to interferometry and optical tweezers, reports Neil Savage. Digital spatial ...

Pupil dilation provides a physiological readout of information gain during the brain's internal process of belief updating in the context of associative learning.

Abstract: In this article, we propose an amplitude-modulated spin-decoupled anisotropic metasurface and its application to a dual-circularly polarized (dual-CP) transmitarray (TA) with suppressed ...

Abstract: The underwater acoustic channel poses a significant challenge among communication mediums due to its time-varying dynamics, long multipath propagation, and severe Doppler shifts. Ensuring ...

This project implements a complete AM radio link on Xilinx FPGA hardware. It uses the Hilbert transform to generate analytic signals for envelope detection and demodulation, demonstrating practical ...
