Science Daily   September 11, 2023 Imaging still scenery with Wi-Fi is considerably challenging due to the lack of motion. The interaction of object edges with the incoming wave, dictated by the Geometrical Theory of Diffraction and the resulting Keller cones, presents new possibilities for imaging with WiFi via edge tracing. Researchers at UC Santa Barbara used the Geometrical Theory of Diffraction and the corresponding Keller cones to trace edges of the objects. They considered the impact of parameters such as curvature of a soft edge, edge orientation, distance to the receiver grid, transmitter location, and other parameters on edge-based WiFi […]
