Abstract
The self-healing property of Bessel beams (BBs) is used to create a robust wireless link at the W-band, maintaining high data rates despite metallic obstructions in their nondiffractive range (NDR). This is demonstrated experimentally using a broadband launcher, which comprises a photonic transmitter and a spline-profile horn, by placing a circular metallic obstacle in the beam’s path. Field measurements show that the BB profile remains intact after the obstacle over the 75–105-GHz band. Power transmission tests reveal a record broadband efficiency of up to 70% (−1.54 dB) at 99 GHz across distances of 10–30 wavelengths. Bit error rate and real-time communication tests confirm the link’s reliability, achieving error-free data transmission at 3 Gb/s using on-off keying (OOK) modulation.
