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 ...

Abstract: Circular phase mode theory is utilized to analyze, design, and demonstrate an improved performance circular retrodirective array (RDA) over a wide bandwidth. The benefits over existing ...

Learn how to use Python to calculate circular and geostationary orbits with simple physics and coding techniques! This video walks through orbital mechanics formulas, gravitational parameters, and ...

The antenna must adhere to more stringent requirements, including multi-band operation, high performance, and compact design, since it is the primary component of satellite communication systems. A ...

Abstract: Estimating angles for coherent signals remains a critical challenge in array signal processing. Traditional spatial smoothing techniques can recover the rank loss caused by signal coherence, ...

Global Navigation Satellite Systems (GNSS), including GPS, GLONASS, Galileo, and BeiDou, have become indispensable for a wide range of applications such as navigation, surveying, and timing ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Espressif Systems’ EchoEar is a compact ESP32-S3 AI chatbot designed for voice interaction and edge AI applications, for smart toys, voice-enabled speakers, and control systems. It features a ...

The easiest way to see the carnage in action is to run it under gdb and break on PyInit__multiarray_umath. You'll see it gets called twice, the second time reentrantly (with a 276-frame backtrace ...

The meme in circulation falsely claimed these turbines existed in Norway. However, there used to be an underwater turbine prototype in the country. Further, underwater tidal turbines are currently in ...

From wound healing to organ development, cells rely on biomechanical signals to navigate their environment, coordinate behavior, and maintain function. Yet, understanding how cells interpret these ...
