Circular sector is a very special geometric form in plane geometry. The following article introduces to you the concept of what a sector is, the formula for calculating the area of a circular sector, ...

Abstract: From MC users' point of view, this paper proposes a practical approach to estimate trajectory error of circular arc interpolation cutter path produced by ...

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 ...
