An OAM Mode Purity Compensation Method for Antenna Array with Elements Offset

In addressing the issue of decreased mode purity caused by the radial offset of array elements in orbital angular momentum waves (OAM) antenna array, a compensation method based on amplitude and phase modulation is proposed. The analysis leads to the determination that amplitude optimization is empl...

Description
Summary:In addressing the issue of decreased mode purity caused by the radial offset of array elements in orbital angular momentum waves (OAM) antenna array, a compensation method based on amplitude and phase modulation is proposed. The analysis leads to the determination that amplitude optimization is employed to achieve effective compensation. Experimental result validates the effectiveness of the proposed compensation method.
