Non-diffracting beams provide blocked-link performance advantages over conventional beams in near-field mmWave communications under specific aperture and blockage conditions.
Mean SNR Gain (Blue Curve): The average advantage of the ND beam is modest, starting at approximately +2.5 dB near t = 0 and peaking at only about +5 dB around t = 0.3
