The planet’s rotation fluctuates as it travels around the sun, and measurements suggest we’re losing more than a millisecond during the long days of summer. By Jacey Fortin This article was updated ...

Python is convenient and flexible, yet notably slower than other languages for raw computational speed. The Python ecosystem has compensated with tools that make crunching numbers at scale in Python ...

Abstract: A low profile and broadband sequential rotation array of circularly-polarized metasurface antenna elements at Ka-band is proposed in this paper. The antenna element includes a ...

Abstract: A novel approach by utilizing the fast mechanical rotation of arrays has been proposed for low sidelobe levels by integrating the rotational time-varying radiation pattern in a short time.
