Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...
Abstract: In this paper, a low-cost K-band phased array antenna is designed for LEO satellite communication. The design reduces the number of T/R components by allowing multiple elements to share a ...
April 15, 2026 • Neuroscientist Paul Nuyujukian likens the brain to a stadium full of people. To eavesdrop on the crowd you could put a microphone in the middle of the stadium. But to understand the ...
Abstract: This study establishes a 2D ultrasonic phased array model for bimetallic composite plates, simulating Delamination Defects, horizontal corrosion, and vertical perforation defects using a ...
In this episode, a faster and more accurate weather radar system provides instantaneous full 3D images of storm cloud activity 10km up into the sky, promising more precise weather forecasting.
End-to-end processing chain: DL-SCH encoding → PDSCH → Precoding → CP-OFDM → CDL/TDL Channel → Receiver (timing sync, demodulation, channel estimation, decoding) with CSI feedback and HARQ ...
This repository implements a full-wave electromagnetic Digital Twin for a planar microstrip antenna array in a cross configuration, specifically designed to rigorously evaluate Direction of Arrival ...
