Abstract: In this paper, a planar double-layer PCB uniform circular array (UCA) system is designed to generate orbital angular momentum (OAM) beams. The UCA system consists of planar directional ...

Could a robot unload your groceries and put them away? A new video makes that future seem not so far away. The latest video from Boston Dynamics shows a humanoid robot moving objects from one ...

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 ...

Big Brother Season 27 entered a new phase in the competition with Vince serving as week 7's Head of Household (HOH). He initially nominated Mickey, Ava, and Kelley for the upcoming elimination, with ...

Abstract: A calibration method based on orbital angular momentum (OAM) is proposed for gain-phase errors in uniform circular array (UCA). The idea of the method is to construct an objective function ...
