That stops neighboring antennas from coupling with each other while still letting the array steer a single precise beam purely by adjusting the phase of light, with no mechanical parts. In tests, the design cut interference between antennas from roughly 100% down to about 1%, while scanning a much broader field of view than earlier chip-based designs.\n\nBecause the chip has no moving parts, it points toward lidar sensors that are smaller, cheaper and more durable than today's spinning units — useful for autonomous vehicles, aerial surveying and construction-site monitoring, where a wide, reliable field of view matters most."}}
