A large-scale antenna array is an enabling technique for millimeter-wave communications. Uniform circular arrays (UCAs) have the spatial invariance property, ensuring the same beamforming performance ...

In this paper, we propose a novel distortion calibration algorithm for uniform circular array (UCA) based on its special structure. A near-field calibration antenna, located in the center of circular ...

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 ...

We sit down Alex Foster's to discuss his debut novel and latest pick for New Scientist bookclub 'Circular Motion' Warning: Spoilers ahead.

A striking composition where swirling colors wrap around a circular frame, creating a sense of movement and energy within a balanced, enclosed space.
