Cover Story: In millimeter-wave (mmW) applications, efforts are focused on improving communication and sensing systems for range, accuracy, frequency coverage, and tunability. However, mmW signals encounter higher propagation losses when obstructed, leading to signal attenuation and reduced coverage. This work introduces a novel automatic synthesizing method (ASM) utilizing genetic algorithms (GA) to design a 3D transmitting conformal meta-lens. The meta-lens enables beam manipulation, including beam deflection using single, dual, and orbital angular momentum (OAM) beams, addressing the challenges of mmW frequencies. The proposed meta-lens offers potential for low-cost, high-gain beam deflection in sensing applications, facilitating wider 2D beam scanning and independent beam deflection enhancements.
