The virtues of geometrical diffraction theory and of uniform asymptotic methods can be combined. Instead of merely matching the local geometry with the geometry of a canonical problem, the exact ...

Researchers have proposed a new foundation that can enable high-quality imaging of still objects with only WiFi signals. Their method uses the Geometrical Theory of Diffraction and the corresponding ...
