This study presents a novel approach to overcome blockage in millimeter-wave and terahertz wireless networks by utilizing self-accelerating beams that can curve around obstacles. The research demonstrates that users in these networks are often located in the near field of the base station, enabling the use of engineered wave fronts to maintain communication links. The study shows that curved beams can maintain a link by curving around an intervening obstacle, and that such beams can utilize the full aperture of the transmitter, even when parts of the aperture have no direct line of sight to the receiver. This approach is particularly suitable for millimeter-wave and terahertz frequencies and opens new possibilities for wave front management in directional wireless networks. The study also explores the bandwidth limitations of curved beams, showing that the curvature of the beam leads to frequency-dependent amplitude and phase responses at the receiver. The research demonstrates that self-accelerating beams can outperform traditional steered Gaussian beams in terms of received power and bit error rate, especially in scenarios where there is an obstacle blocking the direct line of sight. The study further shows that using a caustic beam can significantly improve communication performance by curving around an obstacle, as demonstrated in experiments where a caustic beam was able to recover lost signal power and reduce the bit error rate. The study also discusses the implications of using near-field wave fronts in wireless communications, highlighting that traditional ray optics is not sufficient to capture the behavior of these wave fronts. The research provides a detailed analysis of the link budget for near-field communications, showing that near-field networks require comparatively less transmit energy for operation, which is an important advantage in the THz band where efficient power generation is still an active research area. The study also demonstrates the experimental realization of self-accelerating beams, including the use of phase plates and metasurfaces to generate these beams, and shows that these beams can be used for high data rate wireless communications. The study concludes that trajectory engineering of near-field wave fronts will be an important tool in future physical layer implementations, but that additional research is needed to fully realize the benefits of near-field networking with self-accelerating beams. The research highlights the potential of near-field wave front engineering for future wireless communications, particularly in the THz band, and provides a foundation for further research in this area.This study presents a novel approach to overcome blockage in millimeter-wave and terahertz wireless networks by utilizing self-accelerating beams that can curve around obstacles.
