In this Python physics tutorial, I show you how to draw the celestial sphere using Web VPython! Explore the stars, constellations, and the fundamental concepts behind the celestial coordinate system ...

Abstract: In this paper, a 3D printed slotted waveguide antenna array is proposed for millimeter-wave communication systems at 28 GHz. The design method consists of the characterization of an isolated ...

The vertical design and smart tracking functions of the towers offer big improvements over flat panel arrays. Currently, most solar farms consist of flat panels laid out across the ground or on ...

According to Washington State University, researchers have developed a chip-sized processor and 3D printed antenna arrays that could someday lead to flexible and wearable wireless systems and improved ...

WASHINGTON — Boeing announced it has begun 3D printing the structural panels that form the backbone of satellite solar arrays, a step the aerospace giant says will cut production times in half and ...

Ultrasound tomography (UST) is a medical imaging system that uses the transmission of ultrasound through tissue to create images of the speed of sound. Currently, UST is based on a single-row ...

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 ...

Abstract: In this letter, a general design criterion is proposed for optimizing non-uniform three-dimensional (3D) arrays to enhance near-field capacity in extremely large-scale MIMO (XL-MIMO) ...
